Question

at a local gas station, regular gasoline sells for $2.899 per gallon, while premium gasoline sells for $3.379 per gallon. how much does a person save on 15.25 gallons of gas by buying regular instead of premium?

Answer 1

We first need to find what each type of gasoline equals at 15.25 gallons.
Regular Gasoline:
2.899•15.25
44.20975
Premium Gasoline:
3.379•15.25
51.52975
Let’s subtract regular from premium to see how much you would save.
51.52975-44.20975
7.31975
So you would save $7.31975 when buying regular gas instead of premium.

Answer 2

the person saved $7.32
