Answer is 7.b because of the angles
$567.86
The total amount accrued, principal plus interest, with compound interest on a principal of $500.00 at a rate of 4.25% per year compounded 12 times per year over 3 years is $567.86.
You first subtract 1/5 from both sides
3/4-1/5 = 11/20
3/2x=11/20
now you multiply 2/3 on both sides since you have to get x
11/20 * 2/3
x = 11/30
I hope this helps you
