Question

A contractor purchases 7 dozen pairs of padded work gloves for $103.32. He incorrectly calculates the unit price at $14.76 per pair? What is the correct price?What error did the contractor likely make?

Answer 1

The correct unit price would be $1.23.

The contractor divided 103.32 by 7, resulting in an error.

Explanation:

If we know a dozen equals 12, then 7 dozen looks like:

`7(12)`

Multiply.

`84`

Now we know the contractor purchases 84 pairs of padded work gloves.

Let's find our unit price:

unit price =
`(cost)/(units)`

Substitute.

unit price =
`(103.32)/(84)`

Divide.

unit price =
`1.23`

To find the error of the contractor, let's try substituting in a number (7) provided in the question to see if we get $14.76 per pair:

`(103.32)/(7)`

Divide.

`14.76`
