A particular chemical process deposits scale on the inside of pipes. The scale cannot be removed, but increasing the pumping pressure can maintain the flow through the narrower diameter. The pipe costs $20 per foot to install, and it has no salvage value when it is removed. The pumping costs are $8 per foot of pipe initially, and they increase annually by $ 5 per year starting in year 2. What is the economic life of the pipe if the interest rate is 12% ?

The Barnes Center started selling first-aid kits for students in the pharmacy! When 300 first-aid kits are produced, the average cost is $10 and the marginal cost is $15. Estimate the cost of producing 301 first-aid kits.

Economic Dispatch Question It is required to investigate the economic dispatch of three power plants located in the western part of Victoria. The total load (PD) to be supplied by those power plants is 1500 MW. Assume the cost functions and the generation limits for these power plants are as follows. 350+ 4.2 P₁ + 0.006 P² 600 + 3.1 P₂ + 0.004 P² 500+ 4.2 P3 +0.007 P3 a) b) c) Plant 1: C₁ Plant 2: C₂ Plant 3: C3 = = = 150 ≤ P₁ ≤ 550 350 ≤ P₂ ≤ 700 120 ≤P3 ≤ 400 If the total load is shared among the three power plants equally, what is power generation of each power plant and what is the total operating cost in $/hr in this case. Find the optimal (economic) dispatch of each plant, the incremental operating cost 1, and the total operation cost in $/hr. (You don't need to use the iteration method). If it is expected that those power plant will operate in average 18 hrs a day, how much saving in cost if the economic dispatch operation with shared power operation (in part a).

Every year, there is some form of construction work going on at UF's campus. In January 2018, bids were opened for a new building on campus for UFPD. The bid/construction value of the building was set at $5 Million. Another building of similar structure and purpose is planned with a bid opening in January 2023. What is the expected bid for the new building? It is given that in January 2000, the Florida Construction Cost Index had a value of 5550, while in January 2018, that value was 8000. You can use these price indices to calculate an average inflation in construction costs.

A   Use the profit maximizing rule, MR ≥ MC, buy 300 bags. B   Use the profit maximizing rule, MR ≥ MC, buy 200 bags. C   Use Qb = F/(MR-AVC) where Qb is the breakeven quantity to be determined, the optimal quantity of bags is 300. D   Use Qb = F/(MR-AVC) where Qb is the breakeven quantity to be determined, the optimal quantity of bags is 200.
