To model the situation correctly, let's break down the information provided:
- The total number of items (bags and caps) they plan to give away is 2,000.
- The cost of the bags (b) is $10 each, and the cost of the caps (c) is $5 each.
- They have a total budget of $12,500.
From this information, we can create the following equations:
-
The first equation represents the total number of items: \[ b + c = 2,000 \]
-
The second equation represents the total cost of the bags and caps: \[ 10b + 5c = 12,500 \]
So, the correct pair of linear equations that model this situation is:
- \(b + c = 2,000\)
- \(10b + 5c = 12,500\)
Therefore, the correct response is: b + c = 2,000 ; 10b + 5c = 12,500.
