At an office supply store, Samantha bought 5 notebooks and 2 pens for $9.
Jeffrey bought 3 notebooks and 2 pens for $6. Write a system of equations to represent this situation.

Answer: Let x be the cost of one notebook and y be the cost of one pen. Then we can write the following system of equations to represent the situation:

5x + 2y = 9

3x + 2y = 6

This system represents the fact that Samantha paid $9 for 5 notebooks and 2 pens, and Jeffrey paid $6 for 3 notebooks and 2 pens.

Step-by-step explanation:

Answer: hope this helps ♡

5x + 2x = 9

3x + 2x = 6

Step-by-step explanation:

x = cost of 1 item

Samantha → 5x + 2x = $9

Jeffrey → 3x + 2x = $6

5x + 2x = 9

3x + 2x = 6
