  6. Rental Car Problems • Graph all 3 equations on your graphing calculators. • Under what circumstances would you want to rent from the different companies?

  7. Solving Equations • Consider Go-Go Care Rentals • Daily charge of $28 • Mileage charge of $0.25/mile • If you have $100, how far can you drive on a 1-day rental? • How do we set up an equation to represent this? • What are the steps for solving the equation? • If you have $74, how far can you drive on a 1-day rental?

  8. Solving Equations • A long-distance phone call plan charges $15 per month plus $0.15 for each minute of long-distance phone calls. Your monthly bill was $30.

The shipping cost is $8, plus it costs $2.10 per baseball ordered. Dylan only has $71 to spend on baseballs. How many baseballs, b, can he order?

  9. Solving Equations • 8n + 15 = 103 • 28 + 0.25n = 40 • 1 + 2g = 7 • 2p + 4 = 50 • 12h = 108
