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? ...2480
using 2480 if the profit on regular gas is $0.18 per gallon and the profit on premium gas is $0.20 per gallon, what was the station’s total profit?
Answer provided by our tutors
let premium sold = x & regular sold = x+420
2.55x +2.30(x+420 )=10957
2.55x+2.30x +966 = 10957
4.85 x = 9991
x = 2060
premium sold = 2060+420 = 2480 gallons
