2. Problem 15.58: The cost for constructing a small building in 1999 was $700,000. The construction cost index was 6,059 at that time. The estimated cost of a similar building, when the index value is 10,000, is closest to: a. $424,130 b. $1,155,300 c. $1,347,200. d. $1,384,500. 3. Problem 15.59: An assembly line robot arm with a first cost of $75,000 in 2001 has a cost of $89,750 in 2017. If the equipment cost index for robots was 307 in 1995, and the robot cost increased exactly in proportion to the index, then the value of the index in 2017 is closest to: a. 367 b. 370 c. 395 d. 437
