Complete question :
If the price of an apple is $0.50, the marginal utility per dollar spent for the fifth apple is:
Number of apples ____total utility
2__________________130
3__________________180
4__________________220
5__________________250
6__________________270
7__________________280
Answer:
60
Explanation:
The marginal utility simply refers to the change or extra satisfaction derived with change in consumption.
Hence, the marginal utility of the fifth apple equals :
Difference /change or extra satisfaction derived by consuming one more than 4 apples = (total utility of 5th apple - total utility of 4th apple)
= (250 - 220) = 30
Hence, marginal utility per dollar :
Marginal utility / price per apple
Price per apple = $0.5
Marginal utility of 5th apple = 30
Therefore,
30 / 0.5
= 60
