Question

 A contractor purchases 6 dozen pairs of padded work gloves for ​$87.12. She incorrectly calculates the unit price as ​$14.52 per pair for the expense report. What is the correct unit​ price? What is the​ error?

Answer 1

So, there are 6 dozen pairs of gloves. That amount of gloves costed $87.12. She calculated the amount per pair as 14.52. This was incorrect because she forgot about the majority of the 6 dozen(one dozen is the number 12). So that means there are not 6 pairs of gloves, in fact, there are 72 pairs of gloves. So, now that we have that number, we can correctly calculate the amount of gloves per pair. Now we have 2 answers. The amount per glove and the amount per pair

Answer 1: Each pair of gloves costs $1.21.

Answer 2: Each individual glove costs 61¢(if there is a number under the hundredths place in the price, like in the thousandths, you always round upwards, in this case, the cost was .605, but you round up, making it 61¢)
