Your freind wants to borrow $1,137.45 from your credit card that charges a 14.7% APR you agree to the loan but require your freind to pay the interest of 3.6% APR on the loan and your freind agrees your freind pays you 200.00 at the end of the first month how much good toasts the principal

Answer 1

After one month:

Interest on credit card loan = (14.7/12)% * $1,137.45 = $13.24
Interest on friend's loan = (3.6/12)% * $1,137.45 = $3.42
Total interest charged = $13.24 + $3.42 = $16.66

Amount paid by friend = $200.00
Net increase in principal = $200.00 - $16.66 = $183.34

Therefore, the new principal is:

$1,137.45 + $183.34 = $1,320.79
