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. Store A (0, 0), (5, 20), (10, 40), (15, 60) Store B (0, 0), (4, 14), (8, 28).
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 $5 per gallon.
Store B has the cheaper gasoline. The cost of gasoline at store A is $100 per gallon
From the given data, we can observe that the cost of gasoline at store A increases by $20 for every 5 gallons, while the cost of gasoline at store B increases by $14 for every 4 gallons.
To find out which store has the cheaper cost of gasoline per gallon, we need to calculate the cost per gallon at each store.
At store A:
For every 5 gallons, the cost increases by $20. Thus, the cost per gallon at store A is 20/5 = $4 per gallon.
At store B:
For every 4 gallons, the cost increases by $14. Thus, the cost per gallon at store B is 14/4 = $3.50 per gallon.
Comparing the cost per gallon at both stores, we can conclude that store B has the cheaper cost of gasoline per gallon. Therefore, the correct interpretation is:
Store B has the cheaper cost of gasoline per gallon.
