A specific McDonald’s franchise owner is looking at elasticities of Big Macs. E(p)= 2 (Price), E(i)=1 (Income), E(mt)=1.5 (m=Big Mac, t= Taco). The franchise owner would like to increase the price of Big Macs by 6%. The owner read an economic report saying incomes will grow by 4% next year and due to a strong marketing campaign by Taco Bell, the price of Tacos will fall by 2%.
If the franchise owner currently sells 1,200 Big Macs a day, how many Big Macs a day can the owner expect to sell?
If the owner wants to keep units sold the same at 1,200 per day, by what percentage must the owner change the price of Big Macs?
