An account earns simple interest.
$2000 at 3.5% for 4 years
a. find the interest earned.

$280

b. find the balance of the account.
$

$2280

Step-by-step explanation:

I see you've already found part a, which is to find the amount of interest earned. The next part is easy, to find the balance of the account after four years, just add the interest you've found back to the principal (the original size of the account or loan). $2000 + $280 equals $2280.
