$ 10, 957 gallons of gas sold of which 2802 gallons was regular 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
regular gas: 2802 gallons by the cost of $0.18 per gallon
premium gas: x by the cost of $0.20 per gallon
total of gas is 10,957 gallons => 2802 + x = 10957
x = 10957 - 2802
x = 8155 gallons
total profit = profit from regular gas + profit from premium gas
total profit = 0.18*2802 + 0.20*8155
total profit = $2135.36
the station's total profit was $2135.36.
