Problema Solution

Grace deposits $1000 in a mutual fund earning 9.5% annual interest, compounded monthly.

What is the exponential function that models this situation where, y, is the amount of Grace's investment and ,x, is time in years?

I have A = 1000 (1 + .095/12) 12(x) Is this correct?

If this equation is correct, how do I figure what the balance would be for 5 years and 10 years rounding to the nearest cent.

Thanks!

the correct answer is


A = 1000 (1 + .095/12)^(12*x)


for x = 5 years we have


A = 1000 (1 + .095/12)^(12*5)


A = $1,605.01

for x = 10 years we have


A = 1000 (1 + .095/12)^(12*10)


A = $2,576.06
