jimthompson5910 (jim_thompson5910):

use this calculator here http://www.bankrate.com/calculators/mortgages/loan-calculator.aspx to find the monthly payment for each card

jimthompson5910 (jim_thompson5910):

then add up the monthly payments and tell me what you get

jimthompson5910 (jim_thompson5910):

also tell me what you get for the individual monthly payments

OpenStudy (anonymous):

ok one second!

jimthompson5910 (jim_thompson5910):

ok

OpenStudy (anonymous):

wait idk which ones to put in the calculator

jimthompson5910 (jim_thompson5910):

you do them one at a time

jimthompson5910 (jim_thompson5910):

so at first, you do the Electronics Boutique credit card

jimthompson5910 (jim_thompson5910):

which means you put in 8950 in the Loan amount box you put 3 in the years box and you put 18.4 in the rate box

jimthompson5910 (jim_thompson5910):

then you find the monthly payment, write it down to save it then redo everything over for the second credit card

OpenStudy (anonymous):

for the first one i got 3253.74

jimthompson5910 (jim_thompson5910):

that's way too high

jimthompson5910 (jim_thompson5910):

this is what I'm getting for the first card

OpenStudy (anonymous):

i put a 3 at the end by mistake. i got the same thing the second time haha

jimthompson5910 (jim_thompson5910):

that's good

jimthompson5910 (jim_thompson5910):

what did you get for the second card

OpenStudy (anonymous):

ok one second

OpenStudy (anonymous):

247.02?

jimthompson5910 (jim_thompson5910):

yep, now add the two monthly payments

OpenStudy (anonymous):

572.38 is what i got

jimthompson5910 (jim_thompson5910):

me too

OpenStudy (anonymous):

om good. so now what?

jimthompson5910 (jim_thompson5910):

that's it, that's the answer

jimthompson5910 (jim_thompson5910):

they want the combined monthly payment

jimthompson5910 (jim_thompson5910):

that's how much it costs per month to have those 2 cards (if you want to pay them off in 3 years)

OpenStudy (anonymous):

oh! i see it now im just so tired my common sense is lacking a bit. will you help me with two more?

jimthompson5910 (jim_thompson5910):

sure

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

OpenStudy (anonymous):

expert carD?

jimthompson5910 (jim_thompson5910):

yep that takes the longest at 154 months

OpenStudy (anonymous):

oh that seemed way to easy lol.

jimthompson5910 (jim_thompson5910):

lol like you said, you're tired

jimthompson5910 (jim_thompson5910):

it's late anyway, so it's ok

OpenStudy (anonymous):

i know right lol. well thank you for staying up with me and helping!

jimthompson5910 (jim_thompson5910):

sure thing

OpenStudy (anonymous):

ok and here is the last one:)

jimthompson5910 (jim_thompson5910):

ok one sec while I think

OpenStudy (anonymous):

ok

jimthompson5910 (jim_thompson5910):

does it mention anywhere about the outstanding balances on any of these cards?

OpenStudy (anonymous):

no the picture I sent you was everything

jimthompson5910 (jim_thompson5910):

ok it seems like info is missing, because on this page here http://en.wikipedia.org/wiki/Debt-snowball_method it says "The debt-snowball method is a debt reduction strategy, whereby one who owes on more than one account pays off the accounts starting with the smallest balances first while paying the minimum on larger debts. Once the smallest debt is paid off, one proceeds to the next slightly larger small debt above that, so on and so forth, gradually proceeding to the larger ones later" So basically you pay off the smaller balances first, then you move your way up to the larger balances. But how do you know where to start if you don't know the balances?

jimthompson5910 (jim_thompson5910):

could it be that this problem refers to a previous problem?

OpenStudy (anonymous):

let me checkk

jimthompson5910 (jim_thompson5910):

alright

OpenStudy (anonymous):

no its a totally different problem

jimthompson5910 (jim_thompson5910):

well unfortunately I think there's still missing info, but I think what they mean by snowball method is that you focus all your energy on paying off the largest interest card, then once that's paid off you focus on the next largest until all cards are paid off

jimthompson5910 (jim_thompson5910):

I think the monthly payments will be large at first because you'll be focusing on a card with the largest interest rate however once that card paid off, the payments will go down because the interest rates will go down

jimthompson5910 (jim_thompson5910):

I don't know if there's anything more to say because I don't know anything about the balances or how much you have available to pay per month

OpenStudy (anonymous):

thats okay! thank you for helping me !
