The first Pepsi yields Craig 18 units of utility and the second yields him an additional 12 units of utility. His total utility from three Pepsis is 38 units of utility. The marginal utility of the third Pepsi is:______.
a) 26 units of utility.
b) 6 units of utility.
c) 8 units of utility.
d) 38 units of utility.

Respuesta :

The marginal utility of the third Pepsi is 8 units of utility

Explanation:

Marginal utility attempts to measure the additionally fulfilled use of extra products or services by a customer.

Economists use the idea of marginal demand to assess how much a individual good is likely to pay.

The complete utility of that first two Pepsi is equal to 30(= 18 + 12).  

Thus, the marginal value of the third Pepsi is equal to 8 (= 38-30).
