Is the point (6,-4) a solution to the system above?
You are planning a cookout. A package of hot dog rolls costs $1.50 and a package of hamburger rolls costs $2.00. You can spend a maximum of $15.00 on the rolls and figure you need to have a at least 8 packages of the two types of rolls (combined). The following system of inequalities models the situation.
Can you buy 5 packages of hot dog rolls and 3 packages of hamburger rolls?

Tessa and Ori's teacher gave them each a system of linear equations to solve. They each took a few steps that led to the systems shown in below.
The sum of two numbers is 28 and their difference is 4. Create a system to determine the two numbers. (equation 1,equation 2)
Ken bought 2 video games and 1 DVD for a total of $105. Jerome bought 1 video game and 4 DVDs for a total of $80. Write a system of equations that can be used to find the cost, in dollars, of each video game and each DVD at the store. DEFINE YOUR VARIABLES
A movie theater is offering new low prices for child and adult tickets. The Parr family was able to get an incredible deal. For 2 adult tickets and 3 child tickets, they paid $28.95. The Brady family got the same deal, buying 3 adult tickets and 6 child tickets for $50.91.
A) Write a system of two equations to represent the ticket purchases of each family. DEFINE YOUR VARIABLES.
B) How much does an adult ticket cost?
