a) determine an equation which represents the number of gallons left in George's car as a function of time in hours.

b) determine and equation which represents the amount of miles George has driven as a function of time in hours since 8AM.

c) how many miles will George be able to travel without refilling his tank? At what time will George need to refill his tank by?

Some people believe that​ higher-octane fuels result in better gas mileage for their car. To test this​ claim, a researcher randomly selected 11 individuals to participate in the study. Each participant received 10 gallons of gas and drove his car on a closed course. The number of miles driven until the car ran out of gas was recorded. A coin flip was used to determine whether the car was filled up with​ 87-octane or​ 92-octane first, and the driver did...
