Question

A contractor purchases 7 dozen pairs of padded work gloves for ​$99.96 . She incorrectly calculates the unit price as ​$14.28

Answer 1

The cost or unit price for purchasing each pair of work gloves is $1.19.

The cost of 7 dozen pairs of padded work gloves purchased by the contractor is $99.96.

The incorrect unit price calculated by the contractor is $14.28 per pair.

Now, we know 1 dozen is equal to 12 units.

Therefore,

The number of pairs of gloves purchased = 7 × 12 = 84

As the total cost is $99.96, the cost of each pair will be:

= $99.96 ÷ 84

= $1.19

The error by the contractor was that she didn't consider the word dozen in his calculation. She simply divided the total cost by 7 to calculate the price per pair.

The unit price of purchasing each pair of work gloves is $1.19.
