To model the situation using a pair of linear equations, we can define our variables as follows:
- Let \( p \) be the number of slices of pizza sold.
- Let \( s \) be the number of cans of soda sold.
From the problem description, we have two key pieces of information:
- The total number of items sold is 200.
- The total profit from selling the pizza and soda is $550.
We can translate this information into the following equations:
-
For the total number of items sold, we can write: \[ p + s = 200 \]
-
For the total profit, we know that each slice of pizza sold provides a profit of $3 and each can of soda sold provides a profit of $2. Therefore, we can express the total profit as: \[ 3p + 2s = 550 \]
So, the system of equations representing this situation is:
- \( p + s = 200 \)
- \( 3p + 2s = 550 \)
