We suppose an economy defined by:
Y=10000 ; G = 2000 ; T = 1000 ;
r (real interest rate) = 3%;
C = 400 + 0.6 (Y-T) ;
Lo (factors that affect demand of moeny) = 5 ;
Ms (money supply) = 15000 ;
Mg (growth rate of money) = 10% ;
Yg (growth rate of Y) = 7%

question : If M increase by 3%, the P increase by ? ( the options I have are : 1.22%/1.23%/1.24%/1.25%)
