Compound interest word problem.

Suppose JJ has $1000 that he invests in an account that pays 3.5% interest compounded quarterly. How much money does JJ have at the end of 5 years?

Formula:
A= The amount of money earned after a certain length of time.

P= The amount of money you start with, the principal.

r= The interest rate, in decimal.

t= The amount of time over which the interest is compounded.

n= The number of times the interest in compounded in one year.

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

How do I answer and show work with question, using the formula?

1 answer

Everything you need for the formula is given.
A = 1000
r = .035
t = 5
n = 4

A=P(1+r/n)^nt
= 1000(1 + .035/4)^20
= ....
