Creating and Graphing Linear Equations

Caroline’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?
What is the correct equation to solve?

• 8.95 + 1.5r = 26.95
• 8.95r + 1.5 = 26.95
• 26.95 + 1.5r = 8.95
• 8.95 + 1.5 = 26.95r

The bill for the repair of a computer was $179. The cost of parts was $44, and labor charge was $45 per hour. How many hours did it take to repair the computer?
What is the correct equation to solve?

• 44h + 45 = 175
• 44 + 45h = 175
• 44 + 175 = 45h
• 44 + 45 = 175h

Renting boats on a lake costs $22 per hour plus a flat fee of $10 for insurance. If you paid $98 to rent the boat, how many hours did you rent the boat?
What is the correct equation to solve?

• 22 + 10h = 98
• 22 + 10 = 98h
• 98 + 10 = 22h
• 22h + 10 = 98

Raymond buys bottles of water at $2 each and a large pizza at $13. The total cost was $21. How many bottles of water did Raymond buy?
What is the correct equation to solve?

• 2b + 13 = 21
• 2 + 13b = 21
• 2 + 13 = 21b
• 2b +21 = 13

Jasmine’s cell phone company charges her $35 an month for phone service plus 0.50 for each text message. How many text messages does Jasmine send in a month if her bill was $52?
What is the correct equation to solve?

• 35t + 0.5 = 52
• 35 + 0.5 = 52t
• 35 + 0.5t = 52
• 52 + 0.5t = 35
