Country a and country b start with the same gdp per capita of $50,000. country a's gdp per capita grows at a constant rate of 2.8%, and country b's gdp per capita grows at a constant rate of 1.4%. compute the difference in gdp per capita for these two countries after 100 years. hint: use the rule of 70 to see how long it will take each country to double its gdp per capita.

The rule of 70 is a technique used to forecast how many years would take to a variable to double its value. It consists on dividing number 70 by the growth rate of the variable of interest, which in this case is the GDP of countries A and B.

According to the rule of 70, let's compute how long will take for the GDP of each country to double:

As the growth rates are constant, it is possible to compute the exact value of the GDP of each country in 100 years time using the number of years for output duplication.

this is an outline for the decisions that frankie is going to make

willingness to buy

price or quality

of course, there could be many economic strategies that should be considered important while making decision. opportunity cost is the foremost significant factor while considering any economic option. when you buy something, you should know how much you are forgoing for this product. indeed, you could buy something different with this measure if you changed your mind. willingness to buy shows how much surplus you are earning while making a decision. it is important because it shows you buy what you want or you buy because you have only limited amount of money. the price or quality can be considered as a general economic option that we are applying while buying something. when you buy something, price or quality could be one of the options. indeed, they define the characteristics of the product.
