For Granny Smith apples:

  • At 2 pounds: $3.50 per pound
  • At 3 pounds: $5.25 per pound
  • At 4 pounds: $7.00 per pound

Calculating the cost per pound:

  • At 2 pounds: \( \frac{3.50}{2} = 1.75 \) per pound
  • At 3 pounds: \( \frac{5.25}{3} = 1.75 \) per pound
  • At 4 pounds: \( \frac{7.00}{4} = 1.75 \) per pound

Thus, Granny Smith apples cost $1.75 per pound.

For McIntosh apples:

  • At 2 pounds: $3.70 per pound
  • At 3 pounds: $5.55 per pound
  • At 4 pounds: $7.40 per pound

Calculating the cost per pound:

  • At 2 pounds: \( \frac{3.70}{2} = 1.85 \) per pound
  • At 3 pounds: \( \frac{5.55}{3} = 1.85 \) per pound

Thus, McIntosh apples cost $1.85 per pound.

Comparing the costs:

  • Granny Smith apples: $1.75 per pound
  • McIntosh apples: $1.85 per pound

Conclusion: Granny Smith apples are cheaper at $1.75 per pound.

The correct response is: Granny Smith apples are cheaper at $1.75 per pound.
