Right now, the ratio of nonfiction to fiction is 9:18. If this is reduced, it is a ratio of 1:2, so there needs to be twice as many fiction books as nonfiction.
If we add 6 fiction books, we have 24 fiction books. We can now set up this equation:

Now we cross multiply

We can solve for x by dividing both sides by two, so:
x = 12. There will be 12 nonfiction books.

use a calculator it's way easier but here is the answer
Answer:
NPV, IRR, payback.
Step-by-step explanation:
The best worst decision technique involves the choice modelling. In terms of the overall usefulness in the capital budgeting decisions,
-- the decision rule that is best is the NPV
-- the decision rule that is worst is payback period
The NPV capital budgeting tool provides accurate results and it also assumes cash flow can be reinvested at a discount rate.
The IRR is the second best budgeting tool where it assumes that the cash flows can be reinvested at IRR.
And the worst is the payback where it does not take into account its time value of the money and so it does not yield the correct as well as accurate results.
Therefore, ranking the rules from best to worst is : NPV, IRR, payback.
