To model the situation described, we need to set up a pair of linear equations based on the information given.
Let:
- \( b \) = number of bags
- \( c \) = number of caps
From the problem, we know two key pieces of information:
-
The total number of items (bags and caps) they plan to give away is 2,000. This gives us our first equation: \[ b + c = 2000 \]
-
The total cost of the bags and caps must not exceed their budget of $12,500. The cost of each bag is $10 and the cost of each cap is $5. This gives us our second equation: \[ 10b + 5c = 12500 \]
So, the pair of linear equations that model this situation is: \[ \begin{align*}
- & \quad b + c = 2000 \
- & \quad 10b + 5c = 12500 \end{align*} \]
