You may use a spreadsheet for this one. If \$60 is put in an account that gets 7% per year, and I add \$15 at the end of each year, how much will I have at the end of 8 years

• algebra -

The formula for this would be:
A=P x [(1+APR)^y-1]/APR where A is the final amount in the account, P is the annual contribution,APR is annual percentage rate, and y is the number of years. So, we have:
A=15x[(1+.07)^7-1]/.07=\$129.81
To this, we add the amount of \$60, the amount the account started with, and its' interest over 8 years, which is:
60x(1.07)^8= 103.09, which gives us a grand total of 129.81+103.09=\$232.90 ☺☺☺☺
