If we expand that binomial and at the same time distribute the 5 into the set of parenthesis, what we have is this:

. Combining like terms we have

. As far as I can tell, that is the answer you are looking for, although there are no choices.
Principal, P = $80
monthly interest, i = 5%/12 = 0.05/12
Number of periods, n = 3*12 = 36
Interest earned after three years,
I = P((1+i)^n-1)
=80((1+0.05/12)^36-1)
=12.92 (to the nearest cent.
IT WOULD BE "D" I BELIEVE
HOPE IM RIGHT AND THIS HELPS
36, |-12|=12 and |-3|= 3. Using inverse operations, we multiply instead of dividing and get 36.
