15. Let the present value from production be equal to V = 100, and this value can move either up (with factor u = 1.3) or down (with factor d = 1/u) per period. Suppose that at t-3 management has the option to invest 100 million in order to double the value of production. The risk free rate is 2%. What is the expanded present value of this production facility if management has the opportunity to expand at t = 3? Please round your answer to two decimal places and use a period to indicate the decimal place (e.g. 100.75 instead of 100,75). Enter answer here
