Warm Up 9-10-14 Copy the questions then answer 1. Interpret algebraically: Three less than four time a number 2. James is having a fund raiser dinner. Each attendee is expected to contribute $50. He already has $200 raised and wants to have at least $3,000 after the event. Write an equation/inequality for the situation.

Creating Multi-Variable Equations

Standards and Objectives A.CED.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.   SWBAT create a multi- variable equation or inequality from a word problem SWBAT create a multi-variable equation or inequality from a table

Example 1 Will drives 52 miles an hour. When his friend Mike started calculating his distance, Will had already driven 20 miles. Write an equation for the distance he travels once Mike starts calculating.

Example 2 Jason is purchasing video games for $40 each. The sales tax is 7% and he has a coupon of $20 the total purchase. Write an equation representing how much is the final cost, F, of the order if he ordered G number of games.

Example 1: Creating Linear Equation from Table Create a linear equation for the relationship between the quantities.

Example 2 Create a linear equation for the relationship between the quantities. X 1 2 3 4 Y 7 10

Guided Practice 1. April is moving apartments. Her family needs to rent a U-Haul truck to transport their furniture. The rental company charges $19.99 for the truck. Then, they charge $0.20 per mile. Write an equation that represents how much it will cost to use the truck where x = the miles driven. How much will it cost if the family drives it 40 miles?
