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.
