Answer the following questions below using the 1st table that describes the Project/Investement Details. Ensure to include your steps. Use the "Discrete cash flow and discrete compounding" table for your calculations.

13. The best pump model based on the discounted payback method.

14. Alphas benefit/cost (B/C) ratio.

15. Gammas benefit/cost (B/C) ratio.

16. Is the Alpha pump better than the Beta pump based on the incremental B/C ratio?

If detailed steps are shown and the answers are correct, I will award a like!

Sabino Company is considering the purchase of a new heavy-duty industrial waste-water pump. Suppliers and experts have been consulted and the choice has been narrowed down to three pump models: Alpha, Beta and Gamma. The key parameters of the three pump models are shown below. Parameters Alpha Beta Gamma 1. Initial Cost 330,000 365,000 415,000 ($) 280,000 at EOY1 360,000 at EOY1 450,000 at EOY1 increasing decreasing 2. Revenues increasing annually annually ($) annually thereafter thereafter by thereafter by 2% by 1.0% $10,000 190,000 at 230,000 at EOY1 EOY1 3. Operating increasing increasing 312,000 at EOY1 costs annually increasing annually ($) annually thereafter by thereafter by $20,000 thereafter by $2,400 3% 4.
