A Contractor's Math Error: Calculating Unit Price

Contractor's Purchasing Decision

A contractor purchases 5 dozen pairs of padded work gloves for $69.60. This total expense includes the cost of gloves for a specific work project.

Incorrect Calculation of Unit Price

The contractor incorrectly calculates the unit price as $13.92 per pair for the expense report. This miscalculation leads to inaccurate reporting of expenses.

Correct Unit Price

What is the correct unit price? The correct unit price of the padded work gloves is actually $1.16 per pair, not $13.92 per pair as initially calculated by the contractor.

Identifying the Error

What is the error? The error lies in the contractor's calculation of the price per pair. Instead of dividing the total cost by the total number of pairs, the contractor mistakenly calculated the price per dozen.

Explanation

Answer:

$1.16 per pair of gloves

Explanation:

The contractor calculated the price per dozen instead of the price per pair. The price per dozen is $13.92 while the price per pair is $1.16.

$69.60 ÷ 5 = $13.92 per dozen.

5 dozen (5 • 12) = 60 gloves

69.60 ÷ 60 = $1.16 per pair
