To model the situation with a pair of linear equations, we can define:
- \( p \): the number of pizza slices sold
- \( s \): the number of cans of soda sold
Given the information, we can write two equations:
-
Equation to represent the total number of items sold: \[ p + s = 200 \]
-
Equation to represent the total profit: The profit from the pizza slices is \( 3p \) (since they made $3 profit from each slice) and the profit from the cans of soda is \( 2s \) (since they made $2 profit from each soda). Therefore, the profit equation is: \[ 3p + 2s = 550 \]
So the pair of linear equations is:
- \( p + s = 200 \)
- \( 3p + 2s = 550 \)
