The change in the real money balance is 12%
Explanation:
As per gievn data
GDP growth rate = 8%
Inflation = 4%
The real money change is as follow
Equation
Delta M + Delta V = Delta P + Delta Y
Where
Delta M = Real money change = ?
Delta V = Change in velocity = 0
Delta P = Inflation rate = 4%
Delta Y = GDP growth rate = 8%
Placing values in the above equation
Delta M + 0 = 4% + 8%
Delta M = 12%
Hence the money balance will increase by 12%.
