Solve.Each month a gas station sells x gallons of gas at $1.92/gallon. The cost to the owner of the gas station for each gallon of gas is $1.32. The monthly fixed cost for running the gas station is $37,000. Write an equation that relates the monthly profit, in dollars, to the number of gallons of gasoline sold. Then use the equation to find the monthly profit when 75,000 gallons of gas are sold in a month.
A. P = 0.60x + 37,000; $82,000 B. P = 1.32x - 37,000; $62,000 C. P = 1.92x - 37,000; $107,000 D. P = 0.60x - 37,000; $8000
