"Susan's class spent $43.20 on 41 flowchart templates and packages of graph paper. The templates cost $.90 each and the paper costs $1.25 per package. How many of each did the class buy?"



2. "You and your friend go to a Mexican restaurant. You order 2 tacos and 3 enchiladas, and your friend orders 3 tacos and 5 enchiladas. One bill was $7.80 plus tax, and the other bill was $12.70 plus tax. How much was each taco and enchilada?"

3. "A room is rectangular and has a perimeter of 42 feet. The room is 4 feet longer than it is wide. What are the dimensions of the room?"

As a hint on the first problem, let T be the number of templates bought and G be the number of packages of graph paper. What is the sum of T and G? What was the total cost of the the templates, of the graph paper, and is the sum of those two?
