Answer: $11,233.67, $81,661.70

Explanation:


A = Pe^(rt) where A is the total amount earned, P is the principal amount invested, r is the interest rate, and t is the time it is invested

What do we know?

A = unknown

P = 10,000

r = .07 (converted 7%)

t = 3 years


A = Pe^(rt)


A = 10,000e^((.07)(3))


A = 10,000e^(.21)

A = 10,000(1.2333678)

A = 11,233.3678

rounded to the nearest penny, A = 11,233.37


A = Pe^(rt)


A = 10,000e^((.07)(30))


A = 10,000e^(2.1)

A = 10,000(8.16617)

A = 81661.70
