Let's define two variables to represent the quantities involved:
- Let \( p \) be the number of slices of pizza sold.
- Let \( s \) be the number of cans of soda sold.
Based on the situation described, we can set up the following equations:
-
Equation to represent the total number of items sold: \[ p + s = 200 \]
-
Equation to represent the total profit: The profit from selling pizza is \( 3p \) (as each slice has a profit of $3), and the profit from selling soda is \( 2s \) (as each can has a profit of $2). Therefore, the equation for the total profit will be: \[ 3p + 2s = 550 \]
So, the pair of linear equations that model the situation is:
- \( p + s = 200 \)
- \( 3p + 2s = 550 \)
