Best ResponseYou've already chosen the best response.1since the payment is 5% of the Balance \[P=B_o(1+apr/12)*.05\] \[B_n=B_o(1+apr/12)B_o(1+apr/12)*.05\] \[B_n=B_o(1+apr/12)(1.05)\]

Best ResponseYou've already chosen the best response.1\[B_1=396(1+\frac{.2499}{12})(.85)\] \[B_2=B_1(1+\frac{.2499}{12})(.85)\] \[B_3=B_2(1+\frac{.2499}{12})(.85)\]

Best ResponseYou've already chosen the best response.1thats easy ... 1  .05 = .85 when you dont know how to subtract .... i worked out the recurrsion above in terms of balance and .05 minimum payment

Best ResponseYou've already chosen the best response.1the new balance part of a bill is: old balance, times (1+apr/12) we subtract a minimum payment of .05 from it old balance, times (1+apr/12); minus old balance, times (1+apr/12), times .05 \[B_n=B_{n1}(1+r)B_{n1}(1+r)(.05)\] \[B_n=B_{n1}(1+r)[1.05]\]

Best ResponseYou've already chosen the best response.1i know its .95 .... seeing how i am a human being, i tend to miscalculate some simple process. how did i get 1.05 = .85? its either a typo since 9 and 8 are very close on the keyboard .... or a simply did the subtraction wrong in my head.

Best ResponseYou've already chosen the best response.1the important thing is: a correction is made and we can move on towards a suitable solution

Best ResponseYou've already chosen the best response.1\[B_0 = 396\] \[B_1 = 396(.95)(1+\frac{.2499}{12})\] \[B_2 = (396(.95)(1+\frac{.2499}{12}))(.95)(1+\frac{.2499}{12})\\~~~~=396(.95)^2(1+\frac{.2499}{12})^2\] ... \[B_n = 396(.95)^n(1+\frac{.2499}{12})^n\]looks suitable

Best ResponseYou've already chosen the best response.1start: 396 make a payment, remaining balance is 385 make a payment, remaining balance is 373 make a payment, remaining balance is 362 make a payment, remaining balance is 351
