Find a bank account balance if the account starts with $50,has an annual rate of 7%,and the money left in the account for 8years

So the annual rate is 7% (0.07). The account starts with $50. The money sits in there untouched for 8 years.

1. 50 * 0.07 = 3.5
50 + 3.5=53.5

2. 53.5 * 0.07 = 3.745
53.5 + 3.745 = 57.245

3. 57.245 * 0.07

Now you do the rest. I did up to year two for you, go ahead and complete the rest by yourself. If you have questions please ask I would love to help. :)

Letter b hope it
