Answer:
$13082
Explanation:
Present value = $15,500 in time T= 35 years at rate r= 4.9 %
FV= 15,500 (1.049)^35
= 15,500 (5.33)
= $82,615
Future Value of $15,500 in 34 years at 5.5 percent
= 15,500 (1.055)^34
= 15,500 x 6.174
= $95,697
The amount will be (95,697-82,615)= $13082 higher if you wait for one more year and the interest rate increases.
