An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 646464 gallons per minute while flying through rain clouds.
let ccc represent the number of minutes the plane can fly through clear skies and rrr represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel.
56c+64r < 900056c+64r< 900056, c, plus, 64, r, is less than, 9000
according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff?
