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)
