Ms. Sue,
1st quarter:
$8,000 * 0.06 = $480.
$480 / 4 = $120 Interest for 1st quarter
2nd quarter:
$8,000 + $120 = $8,120
$8,120 * 0.06 = $487.20
$487.20 / 4 = $121.80 Interest for 2nd quarter
3rd quarter:
$8,120 + $121.80 = $8,241.80
I think you can finish the 3rd quarter and do the 4th quarter on your own.
We'll be glad to check your answer.
