  19. You just signed two year contract with Verizon and bought a cell phone for $125, and the monthly charge will be $35 a month. Entry Task So far you have spent $650 on your cell phone plan including your phone purchase, how many months do you have left to pay on your contract? Cost = C Months = M Graph the equation C= 125 + 35M 24 -15 650= 125 + 35M y =-1/3x -125 -125 525 = 35m 9 months /35 /35 15 = m

  20. Brainstorm

  21. INV 29 (1-8) Intersecting Linear models GOAL I can find the rate of change (slope and starting point (y-int) and use the equation to solve a problem.

  22. 1.) Jeff's Rental service charges $40 a day to rent a hammer drill. Jeff's Rental service also sells hammer drills for $360. If someone wanted to buy a hammer drill instead of renting, how many days would they need to use it for it to be better?

  23. 2.) Top Wash charges $0.75 per minute. Dan's car wash charges $9 for a car wash. At how many minutes will both car washes be the same price and what will the price be?

  24. 3.) Rachael and Sabine belong to different local gyms. Rachael pays $50 per month and no registration fee. Sabine pays only $25 per month but had to pay a $75 registration fee. After how many months will Rachael and Sabine have spent the same amount on their gym memberships and what will their price be?

  25. 4.) Rent to Own charges $50 plus $30 a day to rent a video recorder. Rent-a-Center charges $40 a day to rent a video recorder. At how many days will both stores be the same price and what will the price be?

  26. 5.) John's plumbing charges $50 for service job plus $25 an hour. Everlast plumbing charges $35 an hour. At which time will both companies cost the same amount of money and how much will it cost?

  27. 6.) Zoe is comparing two local yoga programs. Yoga- Weigh charges $90 dollars a month and a registration fee of $35. Essence of Yoga charges $80 per month with a $75 registration fee. After how many months will the two schools charge the same amount?

  28. 7.) Abby and Holly are playing games at the arcade in the mall. Abby has $20 and is playing a game that costs 50 cents per game. Holly arrived at the arcade with $22 and is playing a game that costs 75 cents per game. After how many games will the two girls have the same amount of money left?

  29. 8.) While on vacation, Selina won a lot of tickets at two arcades on the boardwalk she was visiting. The first arcade charges $1 to cash in the tickets and gives you 12 cents back on each ticket won, while the second arcade gives you 10 cents back on each ticket and no fee to cash in. In order for Selina to make an equal profit from each arcade, how many tickets must she have won?
