Answer:
The correct answer is option D.
Explanation:
Total cost paid by Lucas = $1,331
Cost of the refrigerator = c
Sales tax on the refrigerator = 8% of c
Charges to deliver refrigerator = $35
![c+8\% \text{of c}+\$35=\$1,331](https://img.qammunity.org/2019/formulas/mathematics/high-school/r47a8tktmh448dmo8zz6tz3a6ucfsp1cmx.png)
![c+0.08c+\$35=\$1,331](https://img.qammunity.org/2019/formulas/mathematics/high-school/zgqdvc2koamcvi23o3zbe981orlploefg5.png)
![c=(\$1,331 -\$35)/(1.08)](https://img.qammunity.org/2019/formulas/mathematics/high-school/p4zobux52a184ztlt9vo4dzb5u83du675j.png)
c = $1200
Amount Sales tax on the refrigerator = 8% of c
![(8)/(100)* \$ 1200=\$96](https://img.qammunity.org/2019/formulas/mathematics/high-school/z2soavclhhnmot4e3art6dveel7egf1xg7.png)
