Juan bought fruit from the grocery store. The variables below define his purchase. Juan’s bananas cost half as much as apples. W
mixas84 [53]

Answer:

B = \frac{1}{2}A

A = 2B

Step-by-step explanation:

Given

Represent apple with A and Banana with B

Required

Determine the relationship between A and B

From the question, we understand that:

B costs half as much as A

This can be represented as:

B = \frac{1}{2} * A

B = \frac{1}{2}A

Multiply both sides by 2

2*B = \frac{1}{2}A*2

2B = A

A = 2B
