Answer 4

it not given there

Answer 5

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

Answer 6

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 :-/

Answer 7

And I think time is in years.

Answer 8

Hi Faman!
Long time!

Answer 9

hey data!

Answer 10

cuz its gona be 400 times .12 for the first year so the total will be 448 aftier the first year

Answer 11

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
