i think you gotta use a exponential function dude, look in your notes and post it here.

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 :-/

And I think time is in years.
anonymous
  • anonymous
Hi Faman! Long time!
Faman39
  • Faman39
hey data!
anonymous
  • anonymous
cuz its gona be 400 times .12 for the first year so the total will be 448 aftier the first year
dumbcow
  • dumbcow
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
