Please please help me with those questions please please help me A water resources engineer is trying to run a cost-benefit analysis for a project. They need to first decide on the planning period (the benefits should be calculated over N years, and N should be determined). If N is too large, then the future benefits in those years (e.g. 70 years from now) will have a very low present value. Therefore, the engineer would like to cut off the planning period after a point when the present equivalent of benefits becomes less than 6.25% of that future benefit. If the interest rate is 8%, use the rule of 72 to determine the duration of the planning period (N). Based on the details in the story what is one difference between Robin Hood and Little John.
