To model the situation with linear equations, we can define two variables:
- Let \( p \) represent the number of slices of pizza sold.
- Let \( s \) represent the number of cans of soda sold.
From the problem, we have two essential conditions:
-
The total number of items sold (pizza slices and soda cans) is 200. This can be represented by the equation: \[ p + s = 200 \]
-
The total profit made from selling the pizza and soda is $550. Given that each slice of pizza has a profit of $3 and each can of soda has a profit of $2, this can be represented by the equation: \[ 3p + 2s = 550 \]
Thus, the pair of linear equations that model this situation is: \[ \begin{align*}
- & \quad p + s = 200 \
- & \quad 3p + 2s = 550 \end{align*} \]
