Cost vs Time by Cost Index Page2005-30-ecoThe cost of a distillation column in the year 2000 is \(x\) dollars. What is the cost of the column in dollars in the year 2010 given the cost indices for the years 2000 and 2010 are 480 and 520 respectively?
- \((520/480)^2x\)
- \((480/520)x\)
- \((520/480)x\)
- \((520/480)^{0.6}x\)

Cost vs Capacity and Time Page2006-60-ecoIn a desalination plant, an evaporator of area 200 m\(^2\) was purchased in 1996 at a cost of $ 300,000. In 2002, another evaporator of area 50 m\(^2\) was added. What was the cost of the second evaporator (in $)? Assume that the cost of evaporators scales as (capacity)\(^{0.54}\). The Marshall and Swift index was 1048.5 in 1996 and 1116.9 in 2002.
