To find the difference in the price level between 2011 and 2010 in Arkanslavia, you can use the equation of exchange formula. The equation is as follows:
Money Supply * Velocity = Price Level * Real Output
In this case, we will use the subscripts "2010" and "2011" to denote the corresponding values for each year.
So, for 2010:
183 million arkollars * 7 (velocity) = Price Level (2010) * 791 arkollars
Similarly, for 2011:
644 million arkollars * 5 (velocity) = Price Level (2011) * 791 arkollars
Now, you need to rearrange the equations to solve for the price level in each year.
For the first equation in 2010:
Price Level (2010) = (183 million arkollars * 7) / 791 arkollars
And for the second equation in 2011:
Price Level (2011) = (644 million arkollars * 5) / 791 arkollars
Finally, to find the difference in the price level between 2011 and 2010, subtract the price level in 2010 from the price level in 2011:
Difference in Price Level = Price Level (2011) - Price Level (2010)
You can plug in the values and calculate the difference to find the answer.
