To find out which orchard would be cheaper for a class of 18 students, we can calculate the total cost for each option.
For Orchard A:
- Admission cost per person: $9
- Number of people (students + chaperones): 18 students + 3 chaperones = 21 people
- Total cost for Orchard A = 21 people × $9/person = $189
For Orchard B:
- Admission cost per person: $10
- Number of people (students + chaperones): 18 students + 1 chaperone = 19 people
- Total cost for Orchard B = 19 people × $10/person = $190
Now we can compare the total costs:
- Orchard A: $189
- Orchard B: $190
Conclusion: Orchard A is cheaper.
So, the correct response is: Orchard A
