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? Give me reasons, before answering the question
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 = 48 hours. Therefore, she earns $25 / hour x 48 hours / week = $1200 a month for 1 math course. So the final answer is 1200.
