    Answer: -

    96 jet engines would be needed to make 24 model airplanes.

    Explanation: -

    We are told that

    1 model airplane = 1 body + 2 wings + 4 jet engines + 1 tailpiece.

    Thus,

    24 model airplanes = 24 x (1 body + 2 wings + 4 jet engines + 1 tailpiece)

    = 24 body + 48 wings + 96 jet engines + 24 tailpiece.

    Thus we see that 96 jet engines would be needed to make 24 model airplanes.
