Compact fluorescent lamps (cfls) have become more popular in recent years, but do they make financial sense? suppose a typical 60-watt incandescent light bulb costs $0.50 and lasts 1,000 hours. a 15-watt cfl, which provides the same light, costs $3.50 and lasts 12,000 hours. a kilowatt-hour of electricity costs $0.101, which is about the national average. a kilowatt-hour is 1,000 watts for 1 hour. if you require a 10 percent return and use a light fixture 500 hours per year, what is the equivalent annual cost of each light bulb?

Your goal is to have $2,000,000. you have a total of $40,000 today. you invest the $40,000 and want to add to it each month. at 10% annual interest, how much do you need to invest each month in order to bring the total up to $2,000,000 30 years from now?

The market price of cheeseburgers in a college town increased recently, and the students in an economics class are debating the cause of the price increase. some students suggest that the price increased because the price of beef, an important ingredient for making cheeseburgers, has increased. other students attribute the increase in the price of cheeseburgers to a recent increase in college student enrollment.1. the first group of students thinks the increase in the price of cheeseburgers is due to the fact that the price of beef, an important ingredient for making cheeseburgers, has increased. (what happened to demand and supply, shift to the right or left)2. the second group of students attributes the increase in the price of cheeseburgers to the increase in college student enrollment. (what happens to demand and supply, shift to the right or left)3. suppose that both of the events you analyzed above are partly responsible for the increase in the price of cheeseburgers. based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the increase in the price of cheeseburgers? (choose a, b,c, or d)a)if the price increase was small, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.b)if the equilibrium quantity of cheeseburgers decreases, then the demand shift in the market for cheeseburgers must have been larger than the supply shift.c)if the equilibrium quantity of cheeseburgers decreases, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.d)whichever change occurred first must have been the primary cause of the change in the price of cheeseburgers.
