Question 4. Let f(t) be the net cash flow after years (in million NOK per year) from a rental property. We think of this as a continuous cash flow, and use continuous discounting with discount rate r = 10% to compute net present values. Find the total net present value from the rental property in the first 10 years when a) f(x) = 100+ 4.6 b) f(1) = 100 - 1.042
