Light-emitting diode (led) light bulbs have become required in recent years, but do they make financial sense? suppose a typical 60-watt incadescent light bulb costs $.45 and lasts for 1,000 hours. a 7-watt led, which provides the same light, costs $2.25 and lasts for 40,000 hours. a kilowatt-hour of electricity costs $.121, which is about the national average. a kilowatt-hour is 1,000 watts for 1 hour. suppose you have a residence with a lot of incandescent bulbs that are used on average 500 hours a year. the average bulb will be about halfway through its life, so it will have 500 hours remaining (and you can’t tell which bulbs are older or newer). if you require a 10 percent return, at what cost per kilowatt-hour does it make sense to replace your incandescent bulbs today? (a negative answer should be indicated by a minus sign. do not round intermediate calculations and round your answer to 6 decimal places, e. g., 32.161616.) solution

Asavings account that pays interest every 3 months is said to have a interest period

A) plot the m1 and m2 money stock in the us from 1990-2015. (hint: you may use the data tools provided by fred.) (b) plot the nominal interest rate from 1960 to 2014. (hint: you can either use the daily interest rates for selected u. s. treasury, private money market and capital market instruments from or the effective federal funds rate fromfred.) (c) the consumer price index (cpi) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. intuitively, the cpi represents the cost of living or the average price level. plot the cpi from 1960 to 2013.(d) the inflation rate is the yearly percentage change in the average price level. in practice, we usually use the percentage change in the cpi to compute the inflation rate. plot the inflation rate from 1960 to 2013.(e) explain the difference between the ex-ante and ex-post real interest rate. use the fisher equation to compute the ex-post real interest rate. plot the nominal interest rate and the ex-post real interest rate from 1960 to 2013 in the same graph.

Suppose the following items were taken from the balance sheet of nike, inc. (all dollars are in millions.) 1. cash $ 2,316.7 7. inventory $ 2,245.6 2. accounts receivable 2,786.2 8. income taxes payable 80.3 3. common stock 2,841.1 9. equipment 1,783.8 4. notes payable 291.2 10. retained earnings 6,162.5 5. buildings 3,959.7 11. accounts payable 2,624.6 6. mortgage payable 1,092.3 perform each of the following. classify each of these items as an asset, liability, or stockholders’ equity, and determine the total dollar amount for each classification. (enter amounts in millions up to 1 decimal place, e. g. 45.5 million.) cash accounts receivable common stock notes payable buildings mortgage payable inventory income taxes payable equipment retained earnings accounts payable assets $ 13092 liability $ 4088.4 stockholders’ equity $ 9003.6 etextbook and media determine nike’s accounting equation by calculating the value of total assets, total liabilities, and total stockholders’ equity. (enter amounts in millions up to 1 decimal place, e. g. 45.5 million.) total assets = total liabilities + total stockholders’ equity
