I'm having a hard time coming up with the right equation to solve this one.
E-Z Stop Fast Gas sold $10,957 worth of gasoline yesterday. Regular grade sold for $2.30 a gallon and premium grade sold for $2.55 a gallon. If the station sold 420 more gallons of regular than of premium, how many gallons of regular were sold?
y=2,060 Gallons of Premium Grade
x=2,480 Gallons of Regular Grade
Hope this helps :)
