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

Question
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?)
