Answer:
It would take exactly 37 years
Explanation:
If we suppose that the economy starts at 10,000 billion dollars in 2020, the economy would only double by the year 2057, reaching a value of 20,399 billion dollars.
If we substract 2020 from 2057, we obtain 37, which is the number of years it took for this economy to double growing at a rate of 2% per year.
