Problem given from a C++ class. Thank you!

A student spends most of his weekend playing and watching sports, tiring him out and leading him to oversleep and often miss his Monday 8AM math class. Suppose that the tuition per semester is $25,000 and the average semester consists of 15 units. If the math class meets three days a week, one hour each day for 15 weeks, and is a four-unit course, how much does each hour of the math class cost the student? Design an algorithm that computers the cost of each math class
