A clothing store sold a certain brand of shirts for X dollars each las

 
­The information presented in the premise can be summarized as shown below 

 ­
the store's total revenue from the sale of the shirts last May was 73 percent less than its total revenue from the sale of the shirts last April

\(M * y = 0.27 * A * x\)  --- (1)

Question: \(y < x?\)

Statement 1

(1) The store sold 70 percent fewer of the shirts last May than it sold last April.

Inference → \(M = 0.3 * A\)

Substituting the value of M in Equation 1

\(M * y = 0.27 * A * x\)

\(0.3 * A * y = 0.27 * A * x\)

As \(A\) represents the number of shirts sold in April, the value of A is not equal to zero. Hence, we can divide both sides of the equation by \(A\). 

\( y = 0.9 * x\)

Hence, we have a relation between \(y\) and \(x\). The statement alone is sufficient to answer the question, Is \(y < x?\) → Yes

Statement 2

(2) The store's total revenue from the sale of 170 of the shirts last April was $3,740.

From the given information we can find the selling price of each shirt in the month of April.

\(x = \frac{3740 }{ 170}\)

We, however, do not have any other information to determine the relationship between \(x\) and \(y\). Hence, the statement alone is not sufficient to conclude whether \(y < x\). 

The statement alone is not sufficient.
