Question

Billy is comparing gasoline prices at two different gas stations. ·at the first gas station, the equation c = 2.80g gives the relationship between g, the number of gallon of gasoline, and c, the total cost, in dollars.·at the second gas station, the cost of 2.5 gallons of gasoline is $8.30, and the cost of 5 gallons of gasoline is $16.60.how much money, per gallon, would Billy save by going to the less expensive gas station?

Answer 1

For the first gas station,

`c=2.80g`

That is, for one number of gallon of gasoline, the cost is, 2.80

For the second gas station, cost of 2.5 gallons of gasoline is $8.30. Therefore, for one gallon if gasoline, the cost is,

`(8.30)/(2.5)=3.32`

Therefore, Billy will save, 3.32 - 2.80 = 0.52 dollars by going to the less expensive gas station.
