Question

two competing airlines create a new marketing plan, charging passengers a fixed amount and then a rate per mile flown. cheapo air: $55.75 plus $0.15 a mile discount airways: $175.55 plus $0.10 a mile a one-way flight from new york to denver is 1,628 miles. if c is the cost of the flight and m is the number of miles flown one way, what is the equation for the cheapest option and how much money do you save? cheapo air, the equation is c = 0.15m 55.75, and i save $38.40 cheapo air, the equation is c = 55.75m 0.15, and i save $299.95 discount airways, the equation is c = 0.10m 175.55, and i save $38.40 discount airways, the equation is c = 175.55m 0.10, and i save $338.35

Answer 1

Cheapo air : c = 0.15m + 55.75...for 1628 miles
                    c = 0.15(1628) + 55.75
                    c = 244.20 + 55.75
                    C = 299.95

discount air : c = 0.10m + 175.55....for 1628 miles
                     c = 0.10(1628) + 175.55
                     c = 162.80 + 175.55
                     c = 338.35

cheapo air has the cheapest option...and u save (338.35 - 299.95) = 
38.40.
