Writing Equations from Word Problems

The video tutorial covers writing equations from word problems, building on previous lessons about expressions. It provides three examples: calculating hours worked based on earnings, determining the number of gym classes attended based on a bill, and finding rental hours for a boat. Each example involves identifying key terms, setting up equations, and solving them. The tutorial concludes with tips for highlighting keywords, determining equal signs, and finding patterns.

What is the main difference between an expression and an equation?

• An equation has variables.

• An expression has an equal sign.

• An equation has an equal sign.

• An expression has variables.

In the problem about Jeff, what is the variable representing?

• The hourly wage

• The number of hours worked

• The total money earned

• The total number of days worked
