Answer:
$1,114.66
Step-by-step explanation:
Data provided in the question:
Monthly periodic rate = 2.15% = 0.0215
current Charges = $189.34
Payment made = $100.00
Finance charge = $21.54
Now,
Previous balance = Finance charges ÷ Rate
= $21.54 ÷ 0.0215
= $1001.86
Unpaid balance = Previous balance + Current charges - Payment
= $1001.86 + $189.34 - $100.00
= $1091.2
New balance = Unpaid balance × ( 1 + Rate )
= $1091.2 × ( 1 + 0.0215)
= $1,114.66
