Question

Jamal bought 5 pair of socks and a shirt. The total cost of all of the items was $70. If the shirt cost $30, how much did each pair of sock cost?

Answer 1

$8

Explanation:

Let the amount of socks be k

Let the amount of shirts bought be s

Since Jamal bought 5 pair of socks and a shirt and totaled $70, hence;

5k + s = 70

If the shirt cost $30, this means s = 30

Substitute s = 30 into the expression;

5k + s = 70

5k + 30 = 70

5k = 70 - 30

5k = 40

k = 40/5

k = 8

Hence each pair of socks costs $8
