_____________.Kevin bought 6 CDs that were each the same price. Including sales tax, he paid a total of $67.20. Each CD had a tax of $0.70. What was the price of each CD before tax?

Answer 1

So in this question we're trying to find the x variable. We know how much our total tax will be, and we also know the total cost, so set up the equation as...

6x + (6*0.70) = 67.20

So now just solve for x.

6x + 4.20 = 67.20

6x = 63.20

Divide both sides by six and you will have solved for the price of each individual CD. Hope this helps! :)
