5
5.6
Rises
Explanation:
Deflation is the reduction in general price levels.
Price levels fell from $10 to $9, thus , deflation has occurred.
Inflation is a persistent rise in general price levels.
Annual rate of change in price level = ($9 / $10) - 1 = -0.01 = -10%
In year 1, $50, will buy $50 / 10 = 5 basket of goods.
In year 2, $50, will buy $50 / $9 = 5.56 basket of goods
As price level falls, the same amount of money can buy more basket of goods. Therefore, the value of money rises as price level falls.
