Final answer:
The expression that can be used to determine the total weight of B baseballs that weigh 5.25 ounces each and s softballs that weigh 6.5 ounces each is Option A: 5.25b + 6.5s.
Step-by-step explanation:
The expression that can be used to determine the total weight of B baseballs that weigh 5.25 ounces each and s softballs that weigh 6.5 ounces each is Option A: 5.25b + 6.5s.
To find the total weight of the baseballs and softballs, we multiply the weight of each baseball, 5.25 ounces, by the number of baseballs, b, and add it to the weight of each softball, 6.5 ounces, multiplied by the number of softballs, s.
For example, if there are 3 baseballs and 4 softballs, we would calculate the total weight as follows:
Total weight = 5.25 * 3 + 6.5 * 4
= 15.75 + 26
= 41.75 ounces.
