Bridget purchased 3 pairs of shoes online. The total bill of $126.81 included a $7.50 shipping charge and 6% tax on the total purchase. If the shoes that Bridget purchased were all priced the same, how much did each pair of shoes cost?

Subtract the $7.50 shipping charge from the bill to find the amount for the shoes plus tax: $126.81 − $7.50 = $119.31. Since 6% tax means the taxed shoe total is 1.06 times the shoes’ price, the three pairs cost $119.31 ÷ 1.06 = $112.56 before tax. Divide by 3: $112.56 ÷ 3 = $37.52 per pair, so the answer is $37.52.
