2. (20 points) Use the following data to make cost estimates: a) The variable frequency drive (VFD) for a 300-horsepower (hp)1/3 motor costs $20,000 How much will a VFD for a 100 hp motor cost? The correlating exponent for VFD in this size range is 0.61. The cost index in 2010 of 147 has been updated to 200 for this year b) Apreiminary estimate for the cost of a parking garage can be made using the unit cost method. If the cost per parking space is $4500, what is the estimated cost of a 500-space parking garage? e) A construction company is contracted to frame 32 wooden houses of the same design in a new subdivision with 200 homes. The first (1st) unit took 400 hours and the carpenter know they can cut about 10% off the time each replication of the same design. Use the learning curve assumption of a constant decrease with each doubling of production to estimate the completion time of the 10 home
