Answer:
The correct answer is the letter b, 5%.
Step-by-step explanation:
The quantitative theory of money analyzes the relationship between money supply and price level, MV = PY, where M is the money supply, V is the speed of money, P is the price level, and Y is the real product. Thus, having Y = 6%, V = constant and M = 30%, we have:
MV = PY
30 (1) = P (6)
P = 30/6
P = 5%
That is, the inflation rate for the Brazilian economy based on the quantitative theory of the currency is 5%.
