Question

A contractor purchases 5 dozen pairs of padded work gloves for ​$67.80. She incorrectly calculates the unit price as ​$13.56 per pair for the expense report. What is the correct unit​ price? What is the​ error?

Answer 1

I think the answer would be $1.13 per pair.

Explanation:

It states that there were 5 dozen gloves, a dozen equals 12, or in this case 12 pairs. 5 dozen means there would be 5×12=60 or 60 pairs. 67.80÷60(pairs)=1.13 dollars PER pair.

The error is that she divided with the 5 dozens, instead of individual pairs.
