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=Premium Grade

x(2.30)+y(2.55)=10,957

x=y+420

y+420(2.30)+y(2.55)=10,957

2.30y+966+2.55y=10,957

4.85y+966=10,957

4.85y=9991

y=2,060 Gallons of Premium Grade

x=2,060+420

x=2,480 Gallons of Regular Grade

Hope this helps :)
