error analysis a contractor purchases 6 dozen pairs of padded work gloves for $81.36. she incorrectly calculates the unit price as $13.56 per pair for the expense report. what is the error? the correct unit price is $ per pair.

Answer

Explanation:

Step1: Calculate total number of pairs

Since 1 dozen is 12, 6 dozen pairs is $6\times12 = 72$ pairs.

Step2: Calculate correct unit - price

The total cost is $81.36$. The unit price $u$ is calculated by dividing the total cost by the total number of pairs, so $u=\frac{81.36}{72}=1.13$.

Answer:

$1.13$
