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.

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.

Answer 1

Store B has the cheaper gasoline. From the graphs:
- Store A: (4 gal, $20) → $20/4 = $5.00 per gallon.
- Store B: (2 gal, $7) → $7/2 = $3.50 per gallon.

So Store B is cheaper at $3.50 per gallon.
