**Question 17 – “What was the amount of money….?”**

OG Explanation is fine.

Statement 1 only tells us the percent and not the actual amounts. Corporate donations could be $40 and noncorporate donations could be $60 or corporate donated or corporate donations could be $400 and noncorporate donation could be $600. INSUFFICIENT.

Statement 2 only tells us that amount from noncorporate donations. We know nothing about the total donations. INSUFFICIENT.

Combining statements 1 and 2: If 40% came from corporate donations and $1.5 million dollars came from noncorporate then we know that $1.5 million represents the other 60% of donations. Therefore the 40% represents $1 million dollars. So the total amount donated must be $2.5 million dollars. BOTH STATEMENTS TOGETHER ARE SUFFICIENT. The answer is C.
