3. (3 pts) Five years ago, when the relevant cost index was 120, a filter membrane unit cost $60K. The unit had a capacity of separating 1,500 gal of ionized solution per hour. Today, it is desired to build a unit with a capacity of 4,500 gal/hour. The cost index is now 110. Experience has shown the economies of scale for this type of equipment can be reflected with a power sizing exponent of (0.6+i/100). What is the estimated cost of the new unit
