A clothing store's revenue last May was 6 percent less than

We can start by using the following variables:

a = revenue last April

b = expenses last April

c = revenue last May

d = expenses last May

We are given that a clothing store's revenue last May was 6 percent less than its revenue last April. Thus,

c = 0.94a

We are also given that the store's revenue last May was greater than its expenses last May, and the store's revenue last April was greater than its expenses last April. Thus:

c > d and a > b

We need to determine whether a - b > c - d, or

Is a - b > 0.94a - d ?

Is 0.06a > b - d ?

Statement One Alone:

The store’s revenue last May was $2,400 less than its revenue last April.

We can create the following equation:

c = a - 2,400

Since c = 0.94a, we can substitute 0.94a for c in the above equation and we have:

0.94a = a - 2,400

2,400 = 0.06a

a = 40,000 and c = 37,600

However, we still cannot determine whether 0.06a > b - d. Statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.

Statement Two Alone:

The store’s expenses last May were 4 percent less than its expenses last April.

Using the information in statement two, we can create the following equation:

d = 0.96b

We can substitute 0.96b for d in the inequality question and we have:

Is 0.06a >b - 0.96b ?

Is 0.06a > 0.04b

Is 6a > 4b ?

Since we are given that a IS GREATER THAN b, then 6a MUST BE GREATER THAN 4b. Statement two alone is sufficient to answer the question.

Answer: B
