Answer:

Options A, C, E

Explanations:

By carefully observing the table attached to this question:

If the number of pounds of banana purchased is represented by p and the cost is represented by c

Since it is a proportional relationship, it can be represented mathematically as:

p = kc

where k is the constant of proportionality

k = p/c

From the table, k = 3/1.47 = 5/2.45 = 9/4.41

k = 2.041

Any value that will represent the missing number of pounds and cost in the table must give a value k = 2.041

Let us consider the options one after the other:

Option A:

k = 2/0.98 = 2.041 (correct)

Option B:

k = 7/4.45 = 1.57 ≠ 2.041 (Wrong)

Option C:

k = 6/2.94 = 2.041 (correct)

Option D:

k = 1/0.54 = 1.85 ≠ 2.041 (wrong)

Option E:

k = 8/3.92 = 2.041 (correct)
