Answer:
Approximately 15%
Explanation:
Given that
Base index = 145
New index = 167
% change in price level = (new index - base index/base index) × 100
Therefore,
% change = (167 - 145/ 145) × 100
= (22/145) × 100
= 0.1517 × 100
= 15.17 %
Thus, there is Approximately 15% increase in price level.
Note: general increases in price is called inflation and decreases in price level is called deflation.
