Problema Solution
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?
Answer provided by our tutors
Suppose, Premium Gallon Sold = X
So, X*2.55 + (X+420)*2.30 =10957
Or, 2.55x + 2.30X +966 =10957
Or, 4.85X = 9991
or, X = 2060 Gallon
So, Regualr gallon Sold = (2060+420) =2480 Gallon
