whats r & t stand for? Im going to need this dumbed down sorry

anonymous · Answer

rate of interest and time. and sorry should have explained the terms 
r = 15.5 
t = 1 month

anonymous · Answer

so ill take the principle times 15.5 times 1?

anonymous · Answer

yups
$$SI = \frac{ 1,853.42 * 15.5 *1 }{ 100 }$$

anonymous · Answer

so whatever that is i divide by 100?? I got 287.28

anonymous · Answer

thats your interest(i.e min. payment) 
but you paid 400 in 1st month 
so you end of month balance = P - 400
