PSAT Math Multiple-Choice Question 792: Answer and Explanation

Question: 792

The percentages of Anita's monthly expenses are portrayed in the below chart. If Anita spent $600 on rent, what was the total of her other expenses for the month?

• A. $600
• B. $900
• C. $1,200
• D. $1,400

Correct Answer: B

Explanation:

(B) Anita's $600 rent represented 40% of her expenses, while 60% of her expenses were spent on everything else. We want to figure out what this 60% was, so we can set up a proportion:

Next, cross multiply:
40x = 36,000
Divide both sides by 40 to determine that x = 900. Therefore, Anita spent $900 on everything else, which is choice (B).
