Two orchards last autumn:
Orchard A: 150 trees, 6,000 kg of apples
Orchard B: 90 trees, 4,500 kg of apples
A grower claims that Orchard B's trees yielded more per tree than Orchard A's. Which choice most effectively uses data from the table to support the claim?
- A. Orchard B's trees yielded 50 kg each (4,500 ÷ 90), compared with 40 kg each at Orchard A (6,000 ÷ 150).Correct
- B. Orchard A produced more apples than Orchard B.
- C. Orchard B has fewer trees than Orchard A.
- D. Orchard B produced 4,500 kg of apples.
Answer: A. Orchard B's trees yielded 50 kg each (4,500 ÷ 90), compared with 40 kg each at Orchard A (6,000 ÷ 150).
Per tree requires dividing yield by trees for both orchards.
Why the other answers are wrong
- B. Orchard A produced more apples than Orchard B.
- Totals point the wrong way and ignore tree numbers.
- C. Orchard B has fewer trees than Orchard A.
- Tree count alone says nothing about yield per tree.
- D. Orchard B produced 4,500 kg of apples.
- A total without a rate.
