MPC is calculated as the change in consumption divided by the change in income =

MPC= ΔY/ΔC
Where,
ΔC = the change in consumption
ΔY = the change in income

Given:
Change in consumption (ΔC) = ₦1,200
Change in income (ΔY) = ₦60,000 - ₦50,000 = ₦10,000
MPC= ₦1,200/₦10,000
=0.12

(2aii)
MPS is calculated as the change in saving divided by the change in income. It can also be found using the relationship between MPC and MPS=

MPS=1−MPC
Given:
MPC = 0.12
MPS = 1−0.12
= 0.88

(2b)
The multiplier (k) is calculated using the formula:

k= 1/1-MPS
Given:
MPC = 0.12
k = 1/1- 0.12
= 1/0.88 ≈ 1.136

(2c)
(PICK ANY FOUR)
(i) The primary determinant of consumption level is the individual's income. Generally, as income increases, so does the ability to consume more goods and services.
(ii) The general price level of goods and services affects consumption. Higher prices typically lead to lower consumption, as individuals may opt to save or spend on essential items.
(iii) Individual preferences and tastes play a significant role in determining consumption habits. Everyone has different preferences that influence what they choose to consume.
(iv) The cost of borrowing and saving, influenced by interest rates, can impact consumption. Lower interest rates may encourage spending, while higher rates can lead to more saving.
(v) The accumulation of wealth, including assets such as savings, investments, and property, can impact consumption levels. Higher wealth often leads to higher consumption.
(vi) Individuals' expectations about their future income can influence their current consumption decisions. If they anticipate higher future income, they may be more inclined to spend now.

SECTION B
(3)
(i) Marginal cost: Marginal cost is the additional cost incurred when producing one more unit of a good or service. It is calculated by dividing the change in total cost by the change in quantity produced. Understanding marginal cost is important for businesses to make decisions about production levels and pricing strategies.

(ii) Wants: Wants refer to the desires or preferences that individuals have for goods and services. Human wants are unlimited, meaning that people always have more desires than they can fulfill. Wants are an important concept in economics because they drive consumption and influence the allocation of resources.

(iii) Scarcity: Scarcity is the fundamental economic problem of having unlimited wants and needs in a world of limited resources. Because resources are limited, individuals, businesses, and governments must make choices about how to allocate these resources in order to satisfy their needs and wants. Scarcity necessitates the need for economic decision-making.

(iv) Choice: Choice refers to the act of selecting among alternatives or options. In economics, individuals, businesses, and governments must make choices about how to allocate scarce resources to best satisfy their wants and needs. Choices involve trade-offs, as selecting one option often means forgoing another. Rational decision-making involves weighing the costs and benefits of different choices.

(v) Opportunity cost: Opportunity cost is the value of the next best alternative forgone when a decision is made. It represents the benefits that could have been gained by choosing an alternative course of action. Understanding opportunity cost is important for decision-making, as it helps individuals and businesses evaluate the trade-offs involved in different choices.

(PICK ANY FOUR)
(i) What to produce: This problem relates to the decision about which goods and services should be produced to best satisfy the wants and needs of the society. It involves determining the mix of goods and services that will maximize utility and welfare for the population.

(ii) How to produce: This problem refers to deciding on the most efficient methods of production to minimize costs and use resources effectively. It involves choosing between different production techniques, technologies, and resource allocations to produce goods and services in the most cost-effective way.

(iii) For whom to produce: This problem concerns the distribution of goods and services among the members of society. It involves deciding how to allocate the produced resources and goods among individuals or groups based on factors such as income, wealth, and needs.

(iv) How much to produce: This problem relates to determining the optimal quantity of goods and services to produce in order to meet demand without oversupplying the market or creating shortages. It involves balancing supply and demand to ensure efficient resource allocation.

(v) How to promote economic growth: This problem focuses on strategies for increasing the overall production and wealth of society over time. It involves decisions about investing in new technologies, infrastructure, education, and other factors that can stimulate economic growth and development.

(vi) How to address externalities: This problem involves dealing with the external costs or benefits that result from economic activities but are not reflected in market prices. Externalities can have positive or negative impacts on society, and addressing them requires policies and regulations to internalize these external costs or benefits.

Utility is a term used in economics to represent the satisfaction or benefit that consumers derive from consuming goods and services. It is a measure of the level of happiness or well-being that individuals receive from the consumption of a particular product or service.

(5b)
(PICK ANY THREE)
(i) Form utility: This type of utility is created by changing the form or shape of a product to make it more useful to consumers. For example, processing raw materials into finished goods adds form utility.
(ii) Place utility: Place utility is created by making goods and services available at convenient locations for consumers. The closer a product is to where consumers are, the higher the place utility.
(iii) Time utility: Time utility is created by providing goods and services at the time when consumers need them. For example, offering seasonal products during the appropriate time of year.
(iv) Possession utility: Possession utility is created by making it easy for consumers to acquire and own goods and services. This can include offering financing options or easy payment terms.
(v) Information utility: Information utility is created by providing consumers with information about products and services to help them make informed purchasing decisions. This can include product reviews, specifications, or comparisons.
(vi) Service utility: Service utility is created by providing additional services along with the product to enhance customer satisfaction. This can include warranties, customer support, installation services, and maintenance services.

(5c)
(PICK ANY TWO)
(i) Total utility is the total satisfaction or benefit obtained from consuming all units of a good or service, WHILE marginal utility is the additional satisfaction gained from consuming one additional unit.
(ii) Total utility is calculated by summing up the utility derived from consuming all units of a good, WHILE marginal utility is calculated by determining the change in total utility when consuming one additional unit.
(iii) Total utility can increase, decrease, or remain constant as more units of a good are consumed, WHILE marginal utility typically decreases as more units are consumed due to the law of diminishing marginal utility.
(iv) Total utility focuses on the overall satisfaction derived from consuming all units of a good, WHILE marginal utility focuses on the incremental satisfaction gained from consuming each additional unit.
(v) Total utility helps in assessing the overall satisfaction derived from consuming a certain quantity of a good, WHILE marginal utility helps in determining the optimal quantity to consume by comparing the additional satisfaction to the additional cost.
(vi) Total utility is derived from the sum of marginal utilities of all units consumed, WHILE marginal utility contributes to the total satisfaction obtained from consuming multiple units of a good.
