Answer:

$373.12

Step-by-step explanation:

Set the equation up as 220 x .087 x 8 because the starting amount is $220 and the interest rate is 8.7% you divide that by one hundred and you get .087 as the interest earned and then 8 is for how many years it was for the final value which is 153.12 and you add that to 220 and you get 373.12 (you add it because that's how much he earned plus the original amount). Hope this helps :)
