The total utilities of the first 5 units of good X are 10,19, 26, 33, and 40 utils, respectively. In other words, the total utility of 1 unit is 10 utils, the total utility of 2 units is 19 utils, and so on. What is the marginal utility of the third unit?

Jackson has $10, which he plans to allocate among three rides at the amusement park. Each ride on the Roller Coaster costs $3.00, on the Bumper Cars, $2.00, and on Splatter Mountain, $1.00. The Table below shows Jackson's utility schedule for the three rides. Given Jackson's budget constraint, what is the maximum utility he can receive from amusement park rides?

true/false

Consider a rational utility maximizing consumer who is choosing between two goods clothing (C) and food (F), where the total utilities of the two goods are independent so that total utility (U) = Utility from clothing + Utility from food. Assume that the utility from these items is outlined below:

Quantity consumed of Food (F):

0

1

2

3

4

5

Utility from F (in utils):

0

12

20

24

26

27

Quantity of clothing (C):

0

1

2

3

4

5

Total Utility from C: (in utils):

0

40

70

90

100

100

Assume further that the price of clothing is $5 per unit and the price of food is $1 per unit, and that the consumer has $18 to spend on the two goods in a given period. Carefully explain how the rational utility maximizing consumer would allocate his/her expenditures on the two goods.
