A = P (1 + r) Superscript t

Which pair of equations would correctly calculate their compound interests?
Herky: A = 500 (1 + 0.08) Superscript 5, Elaina: A = 400 (1 + 0.08) Superscript 6
Herky: A = (500 times 1) + (0.05) Superscript 8, Elaina: A = (400 times 1) + (0.06) Superscript 8
Herky: A = 500 (1 + 0.05) Superscript 8, Elaina: A = 400 (1 + 0.06) Superscript 8
Herky: A = (500 times 1) + (0.05) Superscript 8, Elaina: A = (400 times 1) + (0.05) Superscript 8
