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

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:

$7(12)$

Multiply.

$84$

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

Let's find our unit price:

unit price = $\frac{cost}{units}$

Substitute.

unit price = $\frac{103.32}{84}$

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:

$\frac{103.32}{7}$

Divide.

$14.76$
