If the nominal interest rate is 6 percent and the rate of inflation is 10 percent, then the real interest rate is A. - 16 percent. B. 4 percent. C. - 4 percent. D. 16 percent.

Answer: C. - 4 percent

Step-by-step explanation:

The equation that links all three values is

nominal rate - inflation rate = real rate

6 - 10 = - 4

-4 percent
