I try to do it, but I am so bad in Maths =(
The thing that bother me here, its the billing on the 8/8 and not on the 31 of the month //
1. A credit card account has a $456 balance on 7/8. A purchase of $112 was made on 7%16 and a payment of $342 was made on 7/28. The billing is 8/8
Find the average balance
I found : 5391.405405
2. If the annual interest rate is 15.6% , what is the interest on the card for the billiing period ?
306963.54 - because I : P.R.T
please correct me, I feel like I DID SOMETHING WRONG :T
