Answer 1

To determine if the quantities in the table represent a proportional relationship, we need to check if the ratio of pounds of bananas to cost ($) is constant.

Let's examine the ratios:

• For 2 pounds:
  Cost = $2.50
  Ratio = 2.50 / 2 = 1.25

• For 3 pounds:
  Cost = $3.75
  Ratio = 3.75 / 3 = 1.25

• For 5 pounds:
  Cost = $6.25
  Ratio = 6.25 / 5 = 1.25

• For 7 pounds:
  Cost = $8.75
  Ratio = 8.75 / 7 = 1.25

Since all ratios are equal to 1.25, the quantities in the table are in a proportional relationship.

The answer is 1 (the quantities have a proportional relationship).
