Answer: $18,368.74
Explanation: Future value of annuity refers to the total amount a series of deposit will amount to over a certain period given a certain rate.
Periodic value (P) =$3,100
Rate(r) = 8.5% = 0.085
Time(n) = 5years
FV = Future Value of annuity =?
FV = P[ (((1+r)^n) - 1) ÷ r ]
FV =3,100[(((1+0.085)^3) - 1) ÷ 0.085]
FV = 3100[((1.085^5) - 1) ÷ 0.085]
FV = 3100[(1.50366 - 1) ÷ 0.085]
FV = 3100[0.50366 ÷ 0.085]
FV = 3100[5.9254]
FV = $18,368.74
