Final answer:
Rebecca would need to spend less than $1,260 in housing costs per month to qualify for most loans.
Step-by-step explanation:
The 28/36 rule is a common guideline used by lenders to determine how much of a borrower's income can be allocated towards housing costs and total debt. According to this rule, a borrower's housing costs should be less than 28% of their gross income, and their total debt payments (including housing costs) should be less than 36% of their gross income.
If Rebecca's gross income is $4,500 per month, she would need to spend less than $1,260 (28% of $4,500) in housing costs per month to qualify for most loans.
Therefore, the correct answer is B. 1,260.
