(Section 2.1, #26) Enormous State University’s Math Department offers two courses: FiniteMath and Applied Calculus. Each section of Finite Math has 60 students, and each sectionof Applied Calculus has 50 students. The department will offer a total of 110 sections thissemester, and 6000 students would like to take a math course. How many s ec tions of eachcourse should the department offer in order to fill all sections and accommodate all of thestudents?Step 1: Define the variables.Step 2: Set up the equations.Step 3: Solve; answer the question.4.
