To determine which orchard would be cheaper for a class of 20 students, let's calculate the total costs for each orchard.
Orchard A:
- Admission cost per person: $9
- Total number of people (20 students + 3 chaperones): 23
- Total cost: 23 people x $9 = $207
Orchard B:
- Admission cost per person: $10
- Total number of people (20 students + 1 chaperone): 21
- Total cost: 21 people x $10 = $210
Now compare the total costs:
- Orchard A: $207
- Orchard B: $210
Orchard A is cheaper.
Therefore, the answer is Orchard A.
