Target question: In 2010, what was the net profit from the sale of the two monitors?
Key concept: profit = revenue - expenses
Statement 1: Of the company's expenses in 2010, rent and utilities totaled $500,000.
This just tells us that a PORTION of the company's expenses = $500,000
In addition to not knowing the TOTAL expenses, we also don't know the TOTAL revenue
Statement 1 is NOT SUFFICIENT
Statement 2: In 2010, the company sold 50,000 units of monitor P at $300 per unit and 30,000 units of monitor Q at $650 per unit.
From this information, we COULD determine the company's TOTAL revenue (although we wouldn't waste time doing so on test day)
However, even if we know the company's total revenue, we still have no information about the expenses.
Statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
To answer the target question, we need the companies TOTAL expenses and its TOTAL revenue.
Statement 1 tells us that a PORTION of the company's expenses is $500,000
Statement 2 tells the company's TOTAL revenue
Since we still don't know the company's TOTAL revenue, we can't answer the
target question with certainty
The combined statements are NOT SUFFICIENT
Answer: E
