c) (10 points) If instead, the investment outflow of xo -1 per customer yields a perpetual increased revenue stream given by the cash flow x = (X, X, X3, X4, ...) = (2, 2, 2, 2, ...), compute the net present value (per customer) of investing in this technique at a discount rate of 100%.

(10 points) If instead, the investment outflow of x0=1 per customer yields a perpetual increased revenue stream given by the cash flow x=(x1,x2,x3,x4,)=(2,2,2,2,), compute the net present value (per customer) of investing in this technique at a discount rate of 100%
