Explanation / Answer

P = 2000 dollars
r = 6% = 0.06

a) compounded monthly, so n = 12
t = 10 years

So, we have

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

A = 2000(1 + 0.06/12)^(12*10)

A = 2000(1.005)^120

A = 3638.79 dollars ---> ANSWER

---------------------------------------------------------------

b)
For cont compounding,

A = Pe^(rt)

5000 = 2000e^(0.06 * t)

5000/2000 = e^(0.06t)

ln(5/2) = 0.06t

t = 15.3 years -----> ANSWER
