Melissa bought 6 CDs that were each the same price. Including sales tax, she paid a total of $81.60. Of that total, $4.80 was tax. What was the price of each CD before tax?

Answer 1

Let X be the price of each CD before tax.
The total price of the CDs before tax is 6 CDs * X = <<6*X=6X>>6X.
Melissa paid $81.60 - $4.80 = $<<81.6-4.8=76.8>>76.8 for the CDs without tax.
Thus, 6X = $76.80.
Thus, the price of each CD before tax is X = $76.80 / 6 = $<<76.80/6=12.8>>12.8. Answer: \boxed{12.80}.
