Simple Interest =P*R*T/100
P=principal = 300
R=rate of interest=60%
T=Time=6 months= 1/2year
300*60*1/2*100=9
In the account she will be having P+9$=300+9=309$
P= C(1+ r)^t where P is the money she gets after six months, C is the initial deposit, r is the simple interest rate (in decimal 0.06) and t is the number of years invested (since it's only months, we put down 12 x 0.5). Putting those numbers in the equation, we get $425.56.
