If a consumer receives 22 units of marginal utility for consuming the first can of soda, 20 units from consuming the second, and 15 from the third, the total utility of consuming the three units is A. 57 utils. B. 15 utils. C. 35 utils. D. unknown as more information is needed to determine the answer.

A. 57

Explanation:

Given:

Because Marginal utility refers to utility obtained from the consumption of an additional unit of goods. It is the satisfaction of consumers for the use of additional unit of goods or services.

So the total utility of consuming the three units is:

First can of soda + Second can of soda + Third can of soda

= 22 + 20 + 15 = 57 units

We choose A

answer; (a) calling people who have not shown interest in the product and asking them to buy it;

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
