32. Bob is comparing gasoline prices at two different gas stations. .
At the first station, the equation c=3.40g gives the relationship between g, the number of
gallons of gas and c, the total cost in dollars
At the second station, the cost of 4.5 gallons of gas is $15.75 and the cost of 9 gallons of
gas is $31.50.
How much money, per gallon, would Bob save by going to the less expensive gas station?
