Question

A contractor purchases 4 dozen pairs of padded work gloves for ​$56.16. She incorrectly calculates the unit price as ​$14.04 per pair for the expense report. What is the correct unit​ price? What is the​ error? Why is the​ contractor's unit price​ incorrect?

Answer 1

The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.

Explanation:

It is given 4 dozen pairs of gloves for $56.16.

So, unit price = Divide the price by number of pairs of gloves.

And 1 dozen =12

So 4 dozen =4*12=48 pairs of gloves

So, to find unit rate divide 56.16 by 48.

Unit price =
`(56.16)/(48)= $1.17`

So, the error is she didn't convert the dozen to units.

That made mistake in finding unit price.
