please answer these questions :
Q1-) suppose that the annual rates of growth of real GDP of econoland over a five year period were sequentially as follows: 3 percent, 1 percent, -2 percent, 4 percent, and 5 percent. what was the average of these groth rates in Econoland over these 5 years? what term would economists use to describe what happened in year 3? if the growth rate in year 3 had been a positive 2 percent rather than a negative 2 percent, what would have been the average growth rate?
Q3-) a mathematical approximately called the rule of 70 tells us that the number of years that it will take something that is growing double in size is approximately equal to the number 70 divided by its percentage rate of growth. thus. if Mexico’s real GDP per 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. real GDP per person in Mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the United States. If real GDP per person in Mexico grows at the rate of 5 percent per year, about how long will it take Mexico’s real GDP per person to reach the level that the United States was in 2005?(Hint: How many times would Mexico’s 2005 real GDP per person have to double to reach the united states’ 2005 real GDP per person?)
