Answer:
A. $623
Explanation:
The case says that Ashlynn has a salary of $32,400 per year. So, to find the amount she earns per week you need to divide the salary she gets per year by the number of weeks a year has that are 52:
$32.400/52= $623
As the case says that she should spend no more than one week's pay on rent, the maximum amount per month that she should spend is $623.
