Alexandra's gross annual salary is $38,556. The maximum amount of rent she can afford to pay can be determined by first solving for her monthly gross salary.
Monthly Salary = ($38,556/ 12 months) = $3,213
Assuming that the amount allocated for her rent is 30% of her monthly salary, the maximum amount of rent that she can afford to pay is:
Max allowable rent = $3,213 * 0.30 = $963.90<span />
