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,they sold 2480 gallons of regular grade. 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
Total Profit: ($5704)(0.18) + ($5253)(0.20) = $2077.32
$2.3 per gallon of regular gas "X"
$2.55 per gallon of premium gas "Z"
2480 gallons regular and 2060 premium (simple subtraction)
(2.3)(2480)= $5704
(2.55)(2060)= $5253
Total Profit: ($5704)(0.18) + ($5253)(0.20) = $2077.32
