Answer 1

12.18%

Step-by-step explanation:

Present value = $34,700

Future Value = $173,500

Time (n) = 14 years

Interest Rate = i

Future Value = Present Value * (1+i)^n

$173,500 = $34,700 * (1 + i)^14

(1 + i)^14 = $173,500/$34,700

(1 + i)^14 = 5

1 + i = 5^(1/14)

1 + i = 1.1218284

i = 1.1218284 - 1

i = 0.1218284

i = 12.18%

So, the annual interest rate she must earn is 12.18%.
