Final answer:
The expression that shows at most the number of cobblers Sarah can make is 38 peaches ÷ 10 peaches/cobbler. The maximum number of cobblers Sarah can make is 3 cobblers.
Step-by-step explanation:
To find the maximum number of cobblers Sarah can make with 38 peaches, we need to divide the total number of peaches by the number of peaches required for each cobbler. In this case, each cobbler requires 10 peaches.
The expression that shows at most the number of cobblers Sarah can make is:
38 peaches ÷ 10 peaches/cobbler
By performing the division, we get a quotient of 3.8. Since we can't have a fraction of a cobbler, the maximum number of cobblers Sarah can make is 3 cobblers.
