Dan bought 3 CDs that were each the same price. Including sales tax, he paid a total of $42.60. Each CD had a tax of $0.80. What was the price of each CD before tax?

Answer 1

Let x = the price of a CD before tax in dollars

The equation will be:

3x + 0.80 = 42.60

Subtract 3 both sides:

3x = 41.80

divide 3 both sides:

x = $13.93
