An airline is considering two types of engine systems for use in its planes. Each has the same life and the same maintenance and repair record. System A costs ​$90,000 and uses 40,000 gallons per​ 1,000 hours of operation at the average load encountered in passenger service. System B costs ​$220,000 and uses 25,000 gallons per​ 1,000 hours of operation at the same level. Both engine systems have​ three-year lives before any major overhaul is required. On the basis of the initial​ investment, the systems have 10​% salvage values. If jet fuel costs ​$2.24 a gallon​ (year 1) and fuel consumption is expected to increase at the rate of 5​% per year because of degrading engine​ efficiency, which engine system should the firm​ install? Assume 5,000 hours of operation per year and a MARR of 9​%. Use the AE criterion. What is the equivalent operating cost per hour for each​ engine? Assume an​ end-of-year convention for the fuel cost.

The equivalent annual costs for system A are:

The equivalent annual costs for system B are:

What is the dynamic “capital” view of social class compared to the status view?

Banks are an important part of Australia’s financial system and their business includes taking deposits from the public and providing loans to households and businesses. What is a reserve ratio and explain how a fractional banking system operates? Following the 2008 global financial crisis (GFC), the real-world deposit multiplier tended to be way smaller than the simple multiplier. Explain why that was the case and how it would have affected the money supply in the economy.

The following demand (Q _D) function has been estimated for Fantasy pinball machines:
          
Q _D = 3,500 − 40P + 17.5P _x + 670U + .0090A + 6,500N
  
where P = monthly rental price of Fantasy pinball machines
            P _x = monthly rental price of Old Chicago pinball machines (their largest competitor)
            U = current unemployment rate in the 10 largest metropolitan areas
            A = advertising expenditures for Fantasy pinball machines
            N = fraction of the U.S. population between ages 10 and 30
  
(a)        The point price elasticity of demand (E _D) for Fantasy pinball machines when P = $150, P _x = $100, U = .12, A = $200,000 and N = .35 is  . (round to the second digit after the decimal) {Hint: When you compute Q _D using the provided information, round to the first digit after the decimal.}

The title "How Monetary Policy Changed in Australia on 18th March 2020".

Could you please explain briefly, but clearly and correctly how the RBA managed the cash rate before 18th March, and what has happened since then? (In Australia)

economics is broken into two fields: microeconomics and macroeconomics. Most issues fall in one or the other; however, the COVID-19 virus has implications for both. Limiting your discussion to the U.S., explain why it touches on both microeconomics and macroeconomics and use specific examples to support that position. I recommend beginning with a distinction between the two fields and then proceeding.

Refer to the scenario below to answer the following question(s).

Carol Veldt, owner of Seagull Terrace, watched her investment grow from a small, seaside motel to a thriving year- round resort in just a few years. Atop a cliff overlooking the Maine coast, Seagull Terrace had attracted thousands of visitors during summer, but then faced a tremendous downturn in business during winter. "But, given the established industries in the nearby towns, very little year- round competition, and our close proximity to Portland," Carol added, "I couldn't understand why seasonality had to hit Seagull Terrace so hard!"

So Carol spent her first winter devising a new marketing plan. She put together a promotional package designed to attract business travelers year- round. Carol's plan also involved a seasonal promotional gimmick to be implemented from early winter to late spring that would attract the same numbers as the large summer crowd. Her idea worked! During her second winter, Carol greeted numerous business travelers both satisfied repeat guests as well as new guests who had been snagged by her promotional appeals.

"We still have a long way to go," Carol admitted. "Our delicatessen offers entrees that are a part of the local cuisine, but we'd like to expand that. We provide health club privileges off- site, but we'd like to eventually provide our own. These are goals I hope to achieve in a few years. Our first project, however, included a renovation of our guest rooms and I'm quite proud of the results." Carol then added, "Actually there are so many possibilities. With an indoor pool area, I will eventually offer weekend getaways throughout winter."

23. Carol Veldt has decided to ask selected guests to participate in an extensive survey about their experience at Seagull Terrace and about their requirements in terms of amenities and cuisines.
