Final answer:
If they fill the 25-pound bags, they will have more sandbags, with 267 more bags.
Step-by-step explanation:
To determine the number of sandbags that can be filled, we need to divide the total weight of sand by the weight capacity of each bag.
If the bags can hold 25 pounds of sand, the number of bags can be calculated by dividing 13,350 by 25. This gives us 534 bags.
If the bags can hold 50 pounds of sand, the number of bags can be calculated by dividing 13,350 by 50. This gives us 267 bags.
Therefore, if they fill the 25-pound bags, they will have more sandbags, with 534-267=267 more bags.
