Lesson 14: Four Representations | Unit 2: Introducing Proportional Relationships

The equation $$c = 2.95g$$ shows how much it costs to buy gas at a gas station on a certain day. In the equation, $$c$$ represents the cost in dollars, and $$g$$ represents how many gallons of gas were purchased. Which of the following pairs (gallons of gas, cost) fits this relationship?

The equation $$c = 2.95g$$ shows how much it costs to buy gas at a gas station on a certain day. In the equation, $$c$$ represents the cost in dollars, and $$g$$ represents how many gallons of gas were purchased. What does 2.95 represent in this situation?

The equation $$c = 2.95g$$ shows how much it costs to buy gas at a gas station on a certain day. In the equation, $$c$$ represents the cost in dollars, and $$g$$ represents how many gallons of gas were purchased. Jada’s mom remarks, “You can get about a third of a gallon of gas for a dollar.” Is she correct? How did she come up with that?

There is a proportional relationship between a volume measured in cups and the same volume measured in tablespoons. 3 cups is equivalent to 48 tablespoons, as shown in the graph. For which value y is $$(1, y)$$ on the line you just drew?

There is a proportional relationship between a volume measured in cups and the same volume measured in tablespoons. 3 cups is equivalent to 48 tablespoons, as shown in the graph. What is the constant of proportionality for this relationship?

There is a proportional relationship between a volume measured in cups and the same volume measured in tablespoons. 3 cups is equivalent to 48 tablespoons, as shown in the graph. Which equation represents this relationship? Use $$c$$ for cups and $$t$$ for tablespoons.
