EcoCurls has become a member of the Sustainable Hairdressers Organisation (SHO). As part of her planned expansion, owner-manager Zoe Princeton has been looking to purchase either a Stella water recycler or an Aqua water recycler that the SHO recommends. Both water recyclers are expected to have a five year life, with the Stella having a S10,000 residual value and the Aqua having a S7,000 residual value. EcoCurls required rate of return on investments is 8%. The estimated cash flows for the Stella and the Aqua water recyclers are shown in the table below (excludes any residual value): Option A: Stella Yer YearYear 2Year 3 Year 4 Year 5 Cash inflows savings Cash outlows95,00015,00015,000 15,000 -20,000-15,000 40,00050,000 55,000 55,000 45,000 Net cash flows95,000 25,000 35,000 40,000 35,000 30,000 Option B: Aqua Year 0Year 1 Year 2 Cash inflows savings Cash outflows Year 3 Year 4 Year 5 25,00035,000 40,000 40,000 40,000 70,000 -10,000-10,00010,00012,000-12,000 Net cash flows-70,00015,000 25,000 30,000 28,000 28,000 Required: (1) Calculate the payback period for options A and B (2) Calculate the Net Present Value (NPV) for options A and B.
