Explanation:
The list price is the sale price divided by the difference of 1 minus the result of discount divided by 100.
The formula is given below as
[tex]\begin{gathered} L=\frac{S}{(1-\frac{D}{100})} \\ Where, \\ L=listprice \\ D=DISCOUNT\text{ PERCENTAGE=10.5}\% \\ S=salesprice \end{gathered}[/tex]By substituting the va;lues, we will have
[tex]\begin{gathered} \begin{equation*} L=\frac{S}{(1-\frac{D}{100})} \end{equation*} \\ L=\frac{155}{(1-\frac{10.5}{100})} \\ L=\frac{155}{1-0.105} \\ L=\frac{155}{0.895} \\ L=173.18 \end{gathered}[/tex]Hence,
The final answer is
[tex]L=\text{ \$}173.18[/tex]
