Question

The cost of four sweats and two pairs of jeans is $140. The cost of two sweats and theee pairs of jeans is $150. Define the variable and write a system of equations to represent this situation?​

Answer 1

The system would be:

4x + 2y = 140

2x + 3y = 150

Explanation:

If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.

4x + 2y = 140

2x + 3y = 150
