Question

Here is a “formula” for building a model airplane: 1 body + 2 wings + 4 jet engines + 1 tailpiece → 1 model airplane How many jet engines would be needed to make 24 model airplanes?

Answer 1

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.
