At $450 per month, a student pays $5400 a year in rent. if his annual income is $15000, what percent of his income is spent on rent?

36%

Step-by-step explanation:

The rent paid is a percentage of the net income earned by the student. Logically, if the rate for the rent was at $450 per month for 12 months, this makes $5400 a year in rent.

If the annual income was $15000, the percent of his income is spent on rent

= ($5400/$15000) × 100%

= 36%

It means he spent 36% of his income on rent.
