Mid-Module Assessment Task

Question

 In August, Cory begins school shopping for his triplet daughters.

One day, he bought 10 pairs of socks for $2.50 each and 3 pairs of shoes for 𝑑 dollars each. He spent a total of $135.97. Write and solve an equation to find the cost of one pair of shoes.

Answer 1

The cost of buying the shoes and socks is

10(2.50) + 3d = 135.97 = 25 + 3d

You must now isolate the d:

subtract 25 from both sides:

3d = 110.97

Divide by 3

d = 36.99
