Mario will pay you 360 gold coins for 2 hours of racing G-Karts Luigi will pay you 426 gold coins for 3 hours of racing Go-Karts Find the best offer using three methods: table, rate and graph

Fold your graph paper into fourths RateTable Graph Your Judgment

At the top of your graph paper, make a TABLE for Mario and Luigi’s offers Mario will pay you 360 gold coins for 2 hours of racing Go- Karts HoursPayment Luigi will pay you 426 gold coins for 3 hours of racing Go-Karts HoursPayment

Mario pays more!! Mario will pay you 360 gold coins for 2 hours of racing Go- Karts HoursPayment Luigi will pay you 426 gold coins for 3 hours of racing Go-Karts HoursPayment

Mario will pay you 360 gold coins for 2 hours of racing G-Karts Luigi will pay you 426 gold coins for 3 hours of racing Go-Karts Find the best offer using three methods: table, rate and graph

Mario will pay you 360 gold coins for 2 hours of racing G-Karts Luigi will pay you 426 gold coins for 3 hours of racing Go-Karts To find the RATE, write each offer as a rate fraction 180 coins per hour 360 coins = 2 hours 426 coins = 3 hours 142 coins per hour
