A contractor purchases 7 dozen pairs of padded work gloves for $102.48. She incorrectly calculates the unit price as $14.64 per pair for the expense report. What is the correct unit price? What is the error?

The correct unit price can be calculated by dividing the total price paid by 84 that was the number of pairs of padded work gloves that were bought:

$102.48/84=$1.22

The correct unit price is $1.22.

-The error is that the person calculated the unit price by dividing the total price paid by 7 but the statement indicates that the contractor purchased 7 dozen pairs, which means: 7*12= 84. According to this, the contractor purchased 84 pairs of padded work gloves.
