Case:
Utility, a pivotal concept in economic decision-making, quantifies
satisfaction or pleasure derived from consuming goods. The principle of
utility can assist individuals in making better decisions according to their
priorities and preferences in different aspects of life. In Mr. Ali's
budgetary calculations, the pursuit of utility guides him to make choices
between coffee and pastries, showcasing the intrinsic link between
satisfaction and resource allocation. Mr. Ali is a college student who is
trying to maximize utility within his limited budget. He likes both coffee
and pastries and has Rs.100 to spend on his daily demands. There is a nearby
café that serves coffee and pastries, and he is trying to decide how to
allocate his budget to maximize his utility.
Analyse Ali's choices and spending behaviour to understand how he optimizes
his utility within his budget constraint. The following table provides the
budget, prices, and affiliated utilities of both products.

Law of Diminishing Marginal Utility: The additional utility of consuming
more of a good diminishes as the quantity consumed increases.
Requirements:
1. Calculate the total utility Mr. Ali can derive from his budget if
he spends it entirely on coffee, entirely on pastries, or a combination of
both.
2. How does Ali's budget constraint limit his choices in allocating
his Rs.100?
3. Use the concept of the Law of Diminishing Marginal Utility to
explain why Mr. Ali might choose a combination of coffee and pastries
instead of consuming only one of them.
Answer:
1- Calculating Total Utility:
If Mr. Ali spends his entire budget on coffee:
Total cups of coffee he can buy = Rs. 100 /
Rs. 20 per cup = 5 cups
Total utility from coffee = 5 cups * 5
utility per cup = 25 utils
If Mr. Ali spends his entire budget on pastries:
Total pastries he can buy = Rs. 100 / Rs.
30 per pastry ≈ 3 pastries (as he can't afford 4)
Total utility from pastries = 3 pastries *
7 utility per pastry = 21 utils
If Mr. Ali combines both coffee and pastries:
Let's say he allocates a certain amount to
coffee and the rest to pastries.
For instance, if he buys 3 cups of coffee
(Rs. 60) and 1 pastry (Rs. 30), he spends Rs. 90.
Utility from 3 cups of coffee = 3 cups * 5
utility per cup = 15 utils
Utility from 1 pastry = 7 utils
Total utility from this combination = 15
utils (coffee) + 7 utils (pastry) = 22 utils
2- Budget Constraint:
Mr. Ali's budget constraint of Rs. 100 limits the combinations of coffee
and pastries he can buy. He cannot buy an unlimited amount of both; there's
a maximum quantity he can afford within his budget.
3- Law of Diminishing Marginal Utility:
This law suggests that as a person consumes more of a good, the additional
satisfaction (utility) gained from each additional unit decreases.
-
Mr. Ali might choose a combination of coffee and pastries because of
diminishing marginal utility. Initially, the first cup of coffee or pastry
gives him a high level of satisfaction (5 or 7 utils respectively).
However, as he consumes more of the same item, the additional satisfaction
decreases. So, by combining both, he can maximize his total utility by
balancing the diminishing satisfaction from each item.
Choosing a combination allows him to enjoy some variety while maximizing
the total satisfaction he can derive from his limited budget.
Therefore, to optimize his utility within the budget constraint, Mr. Ali
might choose a combination of both coffee and pastries rather than consuming
only one of them, as it allows him to maximize his overall satisfaction
considering the diminishing marginal utility of each product.
