Suppose you invest $150 a month for 5 years into an account earning 8% compounded monthly. after 5 years, you leave the money, without making additional deposits, in the account for another 21 years. how much will you have in the end?

The first five years you will have 9,720 the account earning at 8% will give you 12 dollars for every 150 a month. After five years the 9,720 without no additional deposits at the 8% monthly rate will give you 777.6 monthly  at the end of the next twenty one years you will have a total of 2,645,395.2 dollars. your welcome!

Set square i think so
