Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cooler alone without the tax?
Let the price of the Cooler before tax = C
C x [1 + 6%] =$7.95
C x 1.06 =$7.95 Divide both sides 1.06
C = $7.95 / 1.06
C =$7.50 - Price of the Cooler before 6% tax.
Let the cost without the tax = C
So
C(1.06) = 7.95 divide both sides by 1.06
C = 7.95/1.06 ≈ 7.5 = $7.50
