The previous statement for your credit card had a balance of $540
You make purchases of $140
And make a payment of $80
Therefore,new credit card balance is
[tex]\begin{gathered} \text{Credit card balance }=540+140-80 \\ \text{Credit card balance }=\text{ \$600} \end{gathered}[/tex]Now using an APR of 24%
The finance charge will be calculated as
[tex]\begin{gathered} Fin\text{ance charge }=\frac{600\times24\times30}{365\times100} \\ Fin\text{ance charge }=\text{\$11.84} \end{gathered}[/tex]Therefore, the finance charge is $11.84
