Answer:

Weather machine, because it has a higher equivalent annual cash flow.

Step-by-step explanation:

Discount rate :

New airplane = 9% = 0.09

Weather machine = 39% = 0.39

Calculate the Equivalent annual cashflow of each :

Using the relation :

New airplane :

(-900+500/1.09) + (600/1.09^2) * 0.09 / (1-1/1.09^2)

(−900+500÷1.09+600÷1.09^2)×9%÷(1−1÷1.09^2)

= 36.2249

Equivalent Annual cashflow of Weather Machine=(−900+550÷1.39+600÷1.39^2+685÷1.39^3)×0.39÷(1−1÷1.39^3)

= 38.0828

Based on the result of the equivalent annual cashflow, the company should opt for investing in weather machine.
