a. Using the regular percentage change method, what is the price elasticity of supply starting at a price of $40 per umbrella and moving to a price of $60 per umbrella? 1000 b. Using the regular percentage change method, when the price of umbrellas falls from $100 per umbrella to $80 per umbrella, the decrease in price is a -1.33 % decrease. The decrease in quantity supplied is a % decrease. Therefore, the elasticity of supply is . c. If the elasticity of supply for umbrellas is 1.1, then an increase in the price of umbrellas of 20% will the quantity supplied by %.

Amathematical approximation called the rule of 70 tells us that the number of years that it will take something that is growing to double in size is approximately equal to the number 70 divided by its percentage rate of growth. thus, if mexico's real gdp per person is growing at 7 percent per year, it will take about 10 years(=70/7) to double. apply the rule of 70 to solve the following problem. real gdp per person in mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the u.s. if real gdp per person in mexico grows at the rate of 5 percent per year: how long will it take mexico's real gdp per person to reach the level that the united states was at in 2005? (hint: how many times would mexico's 2005 real gdp per person have to double to reach the u.s.'s 2005 real gdp per person?
