A) 20 Boeing 727s, and 20 Falcon 20s
B) 10 Boeing 727s, and 20 Falcon 20s
C) 20 Boeing 727s, and 40 Falcon 20s

Answer 2

here is the data

Answer 3

Sort the answer choices by the total number of aircraft (which is what you wish to maximize). Starting from the one with the most aircraft, try each one until you find one that meets the constraints:

\[35000\ge1400b+500f\]\[672000\le42000b+6000f\]
