Draw the short-run ATC, AVC, MC, MR and Demand graphs for a perfectly competitive market experiencing a profit. In each part, show Total Cost (TC), Total Revenue (TR), shade the profit. Clearly label Q for the equilibrium quantity point and P for market price point. a. Draw a profit situation for perfect competition.
b. Draw a loss (not shutdown) situation for perfect competition
c. Draw a loss (not shutdown) situation for monopoly market
d. For this graph show a monopoly and perfect competition on the same graph space for profit. For this question you do not need to show TR, TC or shade a profit, but do show the Quantity perfect competition (Ope), Price perfect competition (Pps), Quantity monopoly (m) and Price monopoly (Pm)

An annuity that goes on indefinitely is called a perpetuity. the payments of a perpetuity constitute a/an series. the equation is: a stock with no maturity is an example of a perpetuity. quantitative problem: you own a security that provides an annual dividend of $170 forever. the security’s annual return is 9%. what is the present value of this security? round your answer to the nearest cent. $

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”
