Final answer:
To find the correct unit price, divide the total amount spent by the total number of pairs purchased.
Step-by-step explanation:
To find the correct unit price, divide the total amount spent by the total number of pairs purchased. In this case, Ali purchased 3 dozen pairs of gloves, which is equivalent to 3 * 12 = 36 pairs. The total amount spent is $90.72. Divide $90.72 by 36 to find the correct unit price:
Correct unit price = $90.72 / 36 = $2.52 per pair
Therefore, the correct unit price for the padded work gloves is $2.52 per pair.
