Foodservice Dietetic Internship Practice Exam

If rent is 4% of income and equals $1,200, what is the total monthly income?

$24,000 $30,000 $28,000 $32,000

Correct Answer:

$30,000

Explanation:

When a portion of income is given as a percentage, you find the total by dividing the portion by the percentage expressed as a decimal. Here, rent is 4% of the income and equals 1,200. Convert 4% to a decimal (0.04) and set up 0.04 × income = 1,200. Solve for income: income = 1,200 ÷ 0.04 = 30,000. So the total monthly income is thirty thousand dollars. Checking quickly: 30,000 × 0.04 = 1,200. If the income were 24,000, 4% would be 960; 28,000 would be 1,120; 32,000 would be 1,280—only 30,000 yields 1,200.
