If the total cost of a package of paper clips including 8% sales tax is $2.70, then what was the price before tax was added
Let the price (before tax ) = P
And the tax was 8% of P = .08P
So
P + .08P = 2.70 simplify
P (1 + .08) = 2.70
P (1.08) = 2.70 divide both sides by 1.08
P = 2.70 / 1.08 = 2.50 = $2.50
