According to the Fisher equation of exchange ($MV=PQ$), which represents the Quantity Theory of Money, suppose that a central bank increases the money supply ($M$) by 15.5%. Over the same period, due to supply-side improvements, the real value of national output ($Q$) increases by 5.0%. Assuming that the velocity of circulation ($V$) remains constant, what is the resulting percentage change in the general price level ($P$)?
