Running out of time? hmm thats a test.

OpenStudy (pphalke):

its homework

OpenStudy (plainntall):

This is more than just math, it is consumer math with special definitions. What is the daily average balance? It is the sum of the balance divided by the number of days in the billing cycle. From 4/25 to 5/8 you have 14 days with a daily balance of $300.00 From 5/9 to 5/13 you have 5 days with $400.00 From 5/14 to 5/24 you have 11 days with $500.00 so that's (14x$300+5x$400+11x$500)/30 right?

OpenStudy (pphalke):

yes I agree @plainntall

OpenStudy (plainntall):

So 13 is $390?

OpenStudy (pphalke):

that's what I got with google calc is it right?

OpenStudy (plainntall):

I am not sure. I know math, but not credit card accounting. From what I am reading it is correct. For 14 you need to find the daily interest rate which if found by dividing the APR by 365 days, the number of days in a standard year.

OpenStudy (pphalke):

how do I do that?

OpenStudy (plainntall):

We are told the APR is 14.6% which is .146 Just divide that by 365

OpenStudy (pphalke):

@Janu16 is 390.00 right for the answer? its consumer math

OpenStudy (pphalke):

its $2500 for 14 is it right

OpenStudy (plainntall):

That doesn't sound correct. I would be upset if I had to pay $2500 interest on an average balance of $390. .146/365 = .0004 or .04 % for the daily interest. To find the interest we multiple the daily average balance times the daily interest rate times the number of days so ($390.00)(.0004)(30) = ?

OpenStudy (pphalke):

I got $4.68 ??

OpenStudy (plainntall):

Great, that's what I got. The new balance would be the ending principal balance plus the interest for the month.

OpenStudy (pphalke):

@agent0smith is the answer right on #13 $390.00?

rebeccaxhawaii (rebeccaxhawaii):

He's afk, ask him later :)

OpenStudy (pphalke):

afk? how do I do number 15 @plainntall is it $4.68-the 390

OpenStudy (plainntall):

It is the end balance ($500) plus the interest ($4.68)

OpenStudy (pphalke):

its 504.68

OpenStudy (bruh_no):

sorry i couldn't help i had a load of test as well! @pphalke
