Q: Cindy was hired to teach 4 math courses which required her to be in the classroom for 48 hours a week altogether. How much did Cindy earn for teaching 1 math course in a month with exactly 4 weeks if her hourly rate per class is $25?

A: In a week, Cindy spends an average of 48 hours/week / 4 courses = 12 hours/week for 1 math course.
In a month, 1 math course is 12 hours/week x 4 weeks/month = <<12*4=48>>48 hours.
Therefore, she earns $25/hour x 48 hours/week = $<<25*48=1200>>1200 a month for 1 math course. The answer is  1,200.
