Suppose it takes 150 credits to graduate. You accumulate credit at the rate of one credit/quarter for each hour
that the class meets per week. For instance, a class that meets three hours each week of the quarter will count for three credits. In addition, suppose that you spend 3.5 hours of study outside of class for each hour in class. A quarter is 10 weeks long. How many total hours, including time spent in class and time spent studying out class, must you invest to get a degree?
