Suppose that the demand for tickets to a concert, QD, is represented by the following equation, where P is the price of concert tickets and Q is the number of tickets sold: QD = 2500 – 20P The supply of tickets, QS, is represented by the equation: QS = –500 + 80P a. Find the equilibrium price and quantity of concert tickets sold. Show your work
b. Carefully graph your results from part a.
c. Calculate the consumer surplus at the equilibrium price and quantity.

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”
