First, find how much the total amount of taxes were by multiplying.
0.50 * 6 = $3 of taxes.
Second, subtract the total tax amount to the final amount to find the amount of all six CD's before tax.
67.80 - 3 = $64.80 total amount before taxes were applied.
Third, divide to find how much each CD cost.
64.80 / 6 = $10.80 per CD.
Best of Luck!
