Question #25

The production costs for the printing of greeting cards increases, though not proportionally, with the number of greeting cards printed. Did the production costs exceed $5 million in the printing of 700,000 greeting cards?

(1) The production costs exceeded $2.5 million in the printing of 400,000 greeting cards.

(2) The production costs exceeded $6 million in the printing of 600,000 greeting cards.

Explanation

With statement (1), if production costs increased proportionally we could state that the printing of 800,000 greeting cards would exceed $5 million. However, since the costs do not increase proportionally, we cannot make such specific assumptions about the costs as the number of cards printed increases. Thus, statement (1) is not sufficient to answer the question.

Statement (2): If at 600,000 cards printed we’re already exceeding costs of $6 million, it is safe to say we will exceed costs of $5 million at 700,000. Sufficient. The correct answer is (B).
