Answer:
Average daily balance is $ 1.809,
Finance charge is $ 0.76
New balance is $ 55.54
Explanation:
Given,
The original account balance = $ 50.51,
After paying $15.00,
New balance = 50.51 - 15 = 35.51,
Again after spending $19.27,
Final balance = 35.51 + 19.27 = 54.78,
∵ Number of days = 25,
So, the average daily balance =
![\frac{\text{Total balance}}{\text{Number of days}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/ibcqgbm1ftb3gtb52jja55rwgpfamrrwma.png)
![=(54.27)/(30)](https://img.qammunity.org/2020/formulas/mathematics/high-school/6rq0704ig8yjnbvjjlb8nny6sc95qsmea8.png)
= $ 1.809
Finance charge annual rate = 18% = 0.18
⇒ Finance charge monthly rate =
![(0.18)/(12)](https://img.qammunity.org/2020/formulas/mathematics/high-school/rv8hkl1d0c8f2z5f6iroetnm3xkhxbjxnq.png)
Thus, the amount of finance charge =
![(0.18)/(12)* 50.51](https://img.qammunity.org/2020/formulas/mathematics/high-school/rx5pvhyc7rxcjozew9sy5vtr12iu7ejiu0.png)
= $0.75765
≈ $ 0.76
New balance = total balance + finance charge = 54.78 + 0.76 = $ 55.54
