Answer: the price of one pair of jeans is $12.56
Explanation:
Let p represent the price of one pair of jeans.
During the tax-free holiday, Aubrey receives $12.33 in change after paying for 3 pairs of equally priced jeans with a $50 bill. Since the 3 pairs of equally priced, it means that the total cost of the 3 pairs of jeans would be 3×p = $3p
Total amount that was collected from him for the 3 pairs of jeans would be 50 - 12.33 = $37.67
Therefore
3p = 37.67
p = 37.67/3 = $12.56
