Assume that on September 30, 2017, AirUS, an international airline based in Germany, purchased a Jumbo aircraft at a cost of euro 42,500,000 (euro is the symbol for the euro). AirUS expects the plane to remain useful for five years (5,000,000 miles) and to have a residual value of euro 4,250,000. AirUS will fly the plane 350 comma 000 miles during the remainder of 2017. Requried:
a. Compute AirUS's depreciation on the plane for the year ended December 31, 2017, using the straight-line method.
b. Compute AirUS's depreciation on the plane for the year ended December 31, 2017, using the units-of-production method.
c. Compute AirUS's depreciation on the plane for the year ended December 31, 2017, using the double-declining method

Acompany manufactures hair dryers. it buys some of the components, but it makes the heating element, which it can produce at the rate of 920 per day. hair dryers are assembled daily, 250 days a year, at a rate of 360 per day. because of the disparity between the production and usage rates, the heating elements are periodically produced in batches of 2,300 units. a. approximately how many batches of heating elements are produced annually? b. if production on a batch begins when there is no inventory of heating elements on hand, how much inventory will be on hand 4 days later? c. what is the average inventory of elements, assuming each production cycle begins when there are none on hand?

Suppose an economist believes that the price level in the economy is directly related to the money supply, or the amount of money circulating in the economy. the economist proposes the following relationship: p=a x m - p=price level - m=money supply - a=a composite of other factors, including real gdp, that change very slowly over time. how might an economist gather empirical data to test the proposed relationship between money and the price level? an economist would persuade the federal reserve to change the money supply to various levels, and observe the resulting changes in the price level. unlike researchers in the hard sciences, economists cannot study complex relationships using data. economists do not usually develop theoretical models of the economy but only analyze summary statistics about the current state of the economy. an economist would look for data on past changes in the money supply, and note the resulting changes in the price level

Which statement best explains the relationship between points a and b? a. consumption reaches its highest point, and then supply begins to fall. b. inflation reaches its highest point, and then the economy begins to expand. c. production reaches its highest point, and then the economy begins to contract. d. unemployment reaches its highest point, and then inflation begins to decrease.
