Unit 1 – Section 9 “Applications of Systems of Equations” Objective: To write systems of linear equations given certain scenarios To solve systems of equations with word problems.

Real Word Problem Solving DEFINE your variables. What does x represent? What does y represent? RELATE the word problem into an equation. WRITE equations that represent the situation. The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.

Real World Problem Solving DEFINE your variables. What does x represent? What does y represent? RELATE the word problem into an equation. WRITE equations that represent the situation. The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. How many children and how many adults attended?

Closing Question Directions: Respond to the following questions. Be prepared to discuss your answers with the class.
