In an article about the financial problems of USA Today, Newsweek reported that the paper was losing about $20 million a year. A Wall Street analyst said that the paper should raise its price from 50 cents to 75 cents, which he estimated would bring in an additional $65 million a year. The paper’s publisher rejected the idea, saying that circulation could drop sharply after a price increase, citing The Wall Street Journal’s experience after it increased its price to 75 cents.
1- What implicit assumptions are the publisher and the analyst making about price elasticity?

According to the midpoint method, the price elasticity of demand between points A and B is approximately
Suppose the price of scooters is currently $25 per scooter, shown as point B on the initial graph. Because the demand between points A and B is
a $25-per-scooter increase in price will lead to

College Tuition Up Again
College gets more expensive again. In-state tuition at public four-year colleges
rose 2.3 percent in 2019-2020, to an average of $10,440 per year. Out-of-state
students paid an average of $26,820 to attend.
Private four-year colleges also saw even bigger price hikes: 3.4 percent-to an
average of $36,880. Tuition prices have been outpacing general inflation rates for
many years.
Source: The College Board.
If tuition keeps increasing at the same rate as in 2019-2020, how much will it cost to complete a degree at a private college in four
years (2019-2023)?
Hint: Future value = Present value x (1 + Growth in prices)
Next year's tuition = This year's tuition x (1 + Growth in prices)
Instructions: Round your responses to the nearest whole dollar.
