    I = Prt I= interest in dollars P = the amount of money r = the rate t = time 200 = (400)*(0.12)(t) t = 200/(400*0.12) This is just a guess, it's been a long time since I've had to do these problems :-/

    ok i'll assume you are only paying the interest each month 400*r*t = 200 monthly rate is 1% 4 t = 200 t = 50 months
