The proportional relationship between the cost of gasoline and the number of gallons of gasoline from Store A and Store B are displayed in the graphs. Use the graphs to interpret the store that has the cheaper cost of gasoline per gallon.

Question

(1 point)
© Store B has the cheaper gasoline. The cost of gasoline is $3.50 per gallon.
• Store A has the cheaper gasoline. The cost of gasoline is $0.25 per gallon.
© Store B has the cheaper gasoline. The cost of gasoline at Store A is $100 per gallon.
• Store B has the cheaper gasoline. The cost of gasoline at Store A is $5 per gallon.

The dot for A is at 15,60
The dot for B is at 8,28

Answer 1

To determine the cost of gasoline per gallon at Store A and Store B from the given points (15, 60) for Store A and (8, 28) for Store B, we need to find the cost per gallon by dividing the total cost by the number of gallons.

For Store A:

• The point (15, 60) means that 15 gallons cost $60.
• Cost per gallon = Total Cost / Number of gallons = $60 / 15 gallons = $4 per gallon.

For Store B:

• The point (8, 28) means that 8 gallons cost $28.
• Cost per gallon = Total Cost / Number of gallons = $28 / 8 gallons = $3.50 per gallon.

Now comparing the two prices:

• Store A: $4 per gallon
• Store B: $3.50 per gallon

Since $3.50 is less than $4, Store B has the cheaper gasoline.
