Answer:
$2070.14
Step-by-step explanation:
Credit card terms vary, as do methods of computing interest and new balance. Here, we'll assume that no payment has been made (<em>in violation of the terms of the credit card</em>), and that the finance charge is only applied to the previous balance.
The finance charge is ...
$1853.68 × 0.249 ÷ 12 = $38.46 . . . . . . . the monthly rate is 0.249÷12
Then the new balance will be the sum of the previous balance, finance charge, and new transaction(s):
$1853.68 +38.46 + 178.00 = $2070.14
_____
<em>Comment on lack of payment</em>
Because no payment has been made, there may also be a late-payment charge added to the balance.
A(R+T)=W
(A×R)+(A×T)=W
AR+AT=W
-AR from both sides
AT=W-AR
divide both sides by A
T=(W-AR)/A
