Elsa solved the following problem.
Lou and George are making chili for the Annual Firefighter’s Ball. Lou uses 2 teaspoons of hot sauce for every 2 cups of chili that he makes, and George uses 3 teaspoons of the same hot sauce for every cup of chili in his recipe. Who has the hotter chili, George or Lou?
Write the related number pairs as ordered pairs and then graph them. Use the graph to compare who has the hotter chili, George or Lou.
Lou’s chili: (2, 2), (4, 4), (6, 6), (8, 8)
George’s chili: (1, 3), (2, 6), (3, 9), (4, 12)
Elsa said that George’s chili was hotter than Lou’s, because the graph showed that the amount of hot sauce in George’s chili was always 3 times as great as the amount of hot sauce in Lou’s chili.
Does Elsa’s answer make sense, or is it nonsense?
