On the graph below please construct a budget line for the expenditure of $10 4. when Arby\'s are $2 each and Wendy\'s are $1 each. A budget line shows the inverse price ration between the two products. b. (1 pt.) Construct a budget line for the expenditure of $16 with Arby\'s and Wendy\'s same prices as in (a) above. Arbys

Solution

Question 3

Marginal utility is calculated as follows -

MU = Change in total utility/Change in consumption

The given table shows that when consumption of jeans increases from 0 to 1, total utility increases from 0 to 150.

So,

Change in total utility = 150 - 0 = 150

Change in consumption = 1 - 0 = 1

MU = Change in total utility/Change in consumption = 150/1 = 150

The MU when consumption increases from 0 to 1 is 150.

In similar manner, MU for other levels of consumption can be calculated.

Following is the complete table -

(b)

The marginal utility is decreasing as the consumption of jeans by the person is increasing.

In other words, marginal utility is declining.

Number of Jeans	Total Utility	Marginal Utility
0	0	X
1	150	(150/1) 150
2	280	(130/1) 130
3	360	(80/1) 80
4	410	(50/1) 50
6	460	(50/2) 25
7	470	(10/1) 10
