Answer:
The correct unit price would be $1.23.
The contractor divided 103.32 by 7, resulting in an error.
Step-by-step explanation:
If we know a dozen equals 12, then 7 dozen looks like:
![7(12)](https://tex.z-dn.net/?f=7%2812%29)
Multiply.
![84](https://tex.z-dn.net/?f=84)
Now we know the contractor purchases 84 pairs of padded work gloves.
Let's find our unit price:
<em>unit price =</em> ![\frac{cost}{units}](https://tex.z-dn.net/?f=%5Cfrac%7Bcost%7D%7Bunits%7D)
Substitute.
<em>unit price = </em>![\frac{103.32}{84}](https://tex.z-dn.net/?f=%5Cfrac%7B103.32%7D%7B84%7D)
Divide.
<em>unit price = </em>
<em />

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:
![\frac{103.32}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B103.32%7D%7B7%7D)
Divide.
![14.76](https://tex.z-dn.net/?f=14.76)
