12. The rule of 72 says that if something is growing by X% per period then it will double approximately every 72/X periods. The periods could be days, months, years, etc. In late February 2020 about 7,000 people outside of China had been infected with the COVID-19 virus and the number was increasing by 9% per day. If the growth rate stayed the same then how many times would be the number of infections double in the next 64 days? a. 8 times so about 56,000 people would be infected b. 1.125 times so about 15,000 people would be infected c. 1.125 times so about 8,000 people would be infected d. 8 times so about 1.8 million people would be infected

A mathematical approximation called the rule of 70 tells us how long it will take for something to double in size if it grows at a constant rate. The doubling time is approximately equal to the number 70 divided by the percentage rate of growth. Thus, if Panama'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: Suppose that real GDP per person in Panama in 2017 was about $13,000 per person, while it was about $52.000 per person in the United States. If real GDP per person in Panama grows at the rate of 2 percent per year, about how long will it take Panama's real GDP per person to reach the level that the United States was at in 2017? (Hint How many times would Panama's 2017 real GDP per person have to double to reach the United States' 2017 real GDP per person?) Instructions: Enter your answer as a whole number. years
