Suppose that over the last twenty-five years a country's nominal GDP grew to three times its former size. In the meantime, population grew by 40 percent and prices rose by 100 percent. What happened to real GDP per person?

b. It increased, but it less than doubled.

Explanation:

Here are the options to this question:

a. It more than doubled.

b. It increased, but it less than doubled.

c. it was unchanged.

d. It decreased.

GDP is the sum of all final goods and services produced in an economy within a given period which is usually a year.

Nominal GDP is calculating GDP using current year prices.

Real GDP is calculating GDP using base year prices.

The question states that nominal GDP tripled and inflation doubled. Therefore, real GDP increases by about 1.5x . Population increased by 1.4x. Therefore, real GDP per person increased, but it less than doubled.

I hope my answer helps you

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
