Agas station charges $2.30per gallon, and $8for a car wash. if drivers fill-up their cars and get a car wash, the gas station reduces the charge per gallon of gas to $2.20. the gas station manager has noticed that this incentive motivates more drivers to get a car wash. assume that the average motorist buys 12 gallons of gas per visit to the gas station, and that five out of a hundred motorists would also get a car wash without the advertised incentive. (a) under those normal conditions, how much money does the gas station take in for every hundred motorists? (b) how many additional car washes would be necessary to at least break even, if gas is lowered by 10 cents a gallon (assuming that the profit on a car wash is negligible)?
