Math Problem Statement
At a corner gas station, the revenue R varies directly with the number g of gallons of gasoline sold. If the revenue is $55.20 when the number of gallons sold is 12, find a linear equation that relates revenue R to the number g of gallons of gasoline. Then find the revenue R when the number of gallons of gasoline sold is 8.5.
