Respuesta :

Answer: 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
