To model the situation with a pair of linear equations, we can define the following variables:
- Let \( p \) be the number of slices of pizza sold.
- Let \( s \) be the number of cans of soda sold.
From the problem statement, we can derive 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 \( 3p \) (since each slice has a profit of $3), and the profit from selling soda is \( 2s \) (since each can has a profit of $2). Therefore, the total profit equation is: \[ 3p + 2s = 550 \]
Thus, the pair of linear equations that model this situation is:
- \( p + s = 200 \)
- \( 3p + 2s = 550 \)
