Explanation:

Hi, first, let me show you the equation that we need to use in order to find the answer for all the questions.

Where:

r = the annual rate of return

n = years from an instant to the other.

So, let´s start to solve the problems

a. n = 1979 - 1787 = 192

So, everything should look like this

so, the answer for a is 5.49%

b. n = 2014 - 1979 = 35

So, everything should look like this

so, the answer for b is 6.99%

c. n = 2014 - 1787 = 227

So, everything should look like this

so, the answer for c is 5.72%

Best of luck.
