Since the cost of the computer is $1999.99 plus 7% tax, then
The total cost of the computer is
![\begin{gathered} C=1999.99+1999.99*(7)/(100) \\ C=2139.9893 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/78liekwez911c7jytho7ql36by0kl7ky4d.png)
Since each installment loan is $203.30 for 12 months, then
The total amount of the loan is
![\begin{gathered} T\mathrm{}L=203.30*12 \\ T\mathrm{}L=2439.60 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ntb219pesaxgygq61ohwxd4wr4g69h176c.png)
The cost of the credit is the difference between them
![\begin{gathered} C\mathrm{}C=2439.60-2139.9893 \\ C\mathrm{}C=299.6107 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/9qjbj5wswssbpctzf9qz3rzdo18e31ef71.png)
The cost of the credit is $299.61 to the nearest cent
