To model the situation, we need to establish the following:
-
Total Items Equation: The total number of bags (b) and caps (c) given away is 2,000. This can be represented by the equation: \[ b + c = 2000 \]
-
Budget Equation: The total cost of the bags and caps must not exceed $12,500. Since the bags cost $10 each and the caps cost $5 each, the budget constraint can be represented by the equation: \[ 10b + 5c = 12500 \]
Thus, the correct pair of linear equations that models the situation is:
- \( b + c = 2000 \)
- \( 10b + 5c = 12500 \)
Therefore, the response that matches this is:
- b + c = 2000; 10b + 5c = 12500.
