Question

If 5 shirts and 8 sweaters cost $222, and 6 shirts and 5 sweaters cost $202, what is the cost of one shirt and what is the cost of one sweater?

Answer 1

Answer: $22 per shirt and $14 per sweater

Explanation:

Let x be shirts and y be sweaters.

We will write equations for the given situation.

5x + 8y = $222

6x + 5y = $202

Next, we will graph both of these equations. The point of intersection will give the prices of one shirt and one sweater.

(22, 14)

➜ $22 per shirt

➜ $14 per sweater
