The Rule of 70 can be applied to calculate the number of years it takes for a variable to double in size or value. According to this rule, you divide the number 70 by the annual growth rate (in percentage terms) to estimate the number of years it would take for the variable to double. For example, if a country's GDP is growing at a rate of 3% per year, it would take approximately 23 years (70/3) for the GDP to double in size. Therefore, the correct answer is C: 70; double.
