Question

Joel earns $1,700 per month every spends for 25 on rent each month what percent of his income does he spend on rent

Answer 1

The answer to this problem is 1.47%

Answer 2

I'm sure Joel pays more than $25/mo for rent. But assuming that the monthly rent actually is $25/mo, then the percentage of his $1700 monthly income that goes to rent is

$25
--------- * 100% = 1.47% (very unlikely).
$1700

If he pays $25/mo, then the answer would be 14.71% (more realistic).
