A tenant earns $3,000 per month and pays $750 a month in rent. What percent of the monthly pay goes to rent?
A20%
B22%
C25%
D30%
Answer & Solution
Correct answer: C. 25%
1. The rent is the part and the monthly pay is the whole.
2. Divide the part by the whole: 750 divided by 3,000.
3. This gives 0.25.
4. Move the decimal point two places to the right and add a percent sign: 25%.
5. 30% would be $900 of rent and 20% would be $600, so both fail a quick check against the actual $750.
