A(t) = P (1 + r/n)^nt

P = 5000, t = 7, r = .09, n = 2

A(7) = 5000 (1 + .09/2)^2(7)

A(7) = 5000 (1 + 0.045)^14

A(7) = 5000 (1.045)^14

A(7) = $9259.72 interest

5000 + 9259.72 = 14259.72

A(t) = P (1 + r/n)^nt

P = 6000, t = 5, r = .0410, n = 4

A(7) = 6000 (1 + .0410/4)^4(5)

A(7) = 6000 (1 + 0.01025)^20

A(7) = 6000 (1.01025)^20

A(7) = $7357.47 interest

6000 + 7357.47 = 13357.47
