To model the situation with a pair of linear equations, we can set up the variables and establish the equations based on the information provided.
Let:
- \( b \) = number of bags
- \( c \) = number of caps
From the information given, we can extract the following two equations:
-
Total items equation: Since they plan to give away a total of 2,000 items (bags and caps), we can write the equation: \[ b + c = 2000 \]
-
Budget equation: The cost of the bags is $10 each and the cost of the caps is $5 each, with a total budget of $12,500. This can be expressed as: \[ 10b + 5c = 12500 \]
Thus, the pair of linear equations that model this situation is: \[ \begin{align*} b + c & = 2000 \quad \text{(1)} \ 10b + 5c & = 12500 \quad \text{(2)} \end{align*} \]
