the cost of one pair of shoes is $36.99
Step-by-step explanation:
Let d represent the cost of one pair of shoes.
While shopping for his triplet girls, he bought 10 pairs of socks for 2.50$ each and 3 pairs of shoes. The expression for the total cost of his purchase is
(2.5 × 10) + (3 × x)
= 25 + 3x
If he spent a total of $135.97, then the equation would be
25 + 3x = 135.97
3x = 135.97 - 25
3x = 110.97
x = 110.97/3
x = 36.99
