Chloe filled up her car with gas before embarking on a road trip
across the country. The capacity of Chloe's gas tank is 12 gallons
and the car uses 0.75 gallons of gas for every hour driven. Make a
table of values and then write an equation for G, in terms of t,
representing the number of gallons of gas remaining in Chloe's gas
tank after t hours of driving.
