Let T be the total one-semester cost (in dollars) of tuition and fees for a student who drove to school and took u units of classes. Answer parts (a) and (b). a. Find an equation for u and T. [Hint: If there is trouble finding the equation, try creating a table of values for u and T.] The equation that describes the relationship between T and u is T = ]. (Simplify your answer. Type an expression using u as the variable.)
