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, then remove the 6% tax: $126.81 − $7.50 = $119.31, and $119.31 ÷ 1.06 ≈ $112.56 for the shoes before tax. Divide that amount by 3 pairs: $112.56 ÷ 3 = $37.52 per pair. The correct choice is $37.52.
