Instructor Overview
In this lesson, students write formulas to represent different rate relationships.
Key Concepts
A formula is a mathematical way of writing a rule for computing a value.
Formulas, like c = 2.50w or d = 20g, describe the relationship between quantities.
 The formula c = 2.50w describes the relationship between a cost and a quantity that costs $2.50 per unit of weight. Here, w stands for any weight, and c stands for the cost of w pounds at $2.50 per pound.
 The formula d = 20g describes the relationship between the distance, d, and the number of gallons of gas, g, for a car that gets 20 miles per gallon.
Goals and Learning Objectives
 Use equations with two variables to express relationships between quantities that vary together.
