Answer:
After three years you have earned $3,755.60
Explanation:
The first year you start with $15,500 on account and earn $1,162.50 as interest
At the end of the first year the bank account is $16,662.50
The second year you start with $16,662.50 and earn $1,249.69 as interest
So at the end of the second year you have a sum of $17,912.19
Then on the third year you start with $17,912.19 and earn an interest of $1,343.41
So at the end of the third year the total of the bank account is $19,255.60
Now, if you sum the three interests $1,162.50+$1,249.69+$1,343.41 the total is $3,755.60 and this is your answer.
