Paying the Price - Rational Equations

Group Work,Take-Home Quiz,In-Class Activity

Time Required: 45 minutes

Objectives: Solve for the missing value in a formula involving a rational expression.

Prerequisites: Solve rational equations for a given value (an introduction to the topic)


The purpose of this activity is for students to explore the use of rational equations to solve practical problems.

This activity uses the standard bookstore formula for calculating the price of textbooks and materials. This is not the standard simple percent increase that most textbooks use. Formulas have been submitted by the Mesa College bookstore. In addition, the student is given the formula for calculating the monthly payments on a loan.

This is a good group activity as it creates some good discussion.
