About the Lesson

This lesson involves setting up and solving systems of equations. As a result, students will:

  • Write a system of linear equations with three variables to model a real-world application.
  • Solve their system of equations.
  • Utilize their solutions to determine the number of calories contained in a gram of carbohydrate, a gram of protein, and a gram of fat, and also obtain the formula for finding basal metabolic rate (BMR).
  • Write and solve additional equations to further explore information about calories and diet.
