Answer:

The correct answer is D.

Explanation:

Giving the following information:

Corey deposits $1,000 in a savings account that pays an annual interest rate of 5 percent. Throughout a year, the inflation rate is 1.7 percent.

I will separate the answer in two different calculations. First, compute the nominal increase. Then, determine the real increase in purchasing power:

Nominal increase= 1,000*0.05= 50

Real increase= (1,000*0.05) - (1,000*0.017)= $33
