Explanation:
Answer:
The interest rate is 7.83%
Explanation:
The winner price in the year 1895 = $190
The winner price in the year 2014 = $1490000
Time duration between, 2014 – 1895 = 119 years
Now we have to find the interest rate at which the winner price has been increased. Thus, use the below formula to find the interest rate.
Future value = present value (1+ r)^n
Future value = $1490000
Present value = $190
n = 119
Now insert the values in the formula.
1490000 = 190(1 + r)^119
1490000 / 190 = (1+r)^119
r = 0.07826 or 7.83%
Answer:
With a population growth of 2%, the GDP has to grow 12.6% per year in order to real GDP per person double in 7 years.
Explanation:
It is necessary to state the formula to calculate the GDP growth per person in 7 years and some assumptions. Defining as base of population and GDP the number 100 (aleatory picked) we can write our equation: GDP per person in year 7 = 100(1+x)^7/100(1+0.02)^7=2 In this equation X is the fixed percentage of GDP growth. By iteration process, we get that X=12.6%
