Final answer:
Selling 25 balloons at $1.25 each will raise $31.25 in revenue. After subtracting the initial cost of $10 for the balloons, the net money raised would be $21.25.
Step-by-step explanation:
If you want to calculate the amount of money you will raise by selling 25 balloons at $1.25 each, you multiply the number of balloons by the selling price per balloon. Therefore, the calculation would be 25 balloons × $1.25 per balloon, which equals $31.25. This is the total revenue you would earn from selling the balloons, not accounting for the initial cost of the box. However, since you want to know the total money raised, you should also subtract the amount you spent on buying the balloons. You spent $10 on the box of balloons. So, the net money raised would be $31.25 (gross revenue) - $10 (cost) which gives us $21.25.
