To obtain Drian's final bill, the following steps are necessary:
Step 1: Find the separate amounts Drian paid as tax, and as tip, as shown below:
- Tax = 6% of $ 150, which is:
[tex]\begin{gathered} \text{Tax = }\frac{6}{100}\times150=\frac{900}{100}=9 \\ \Rightarrow\text{ Tax = 9 dollars} \end{gathered}[/tex]- Tip = 15% of $ 150, which is:
[tex]\begin{gathered} \text{Tip}=\text{ }\frac{15}{100}\times150=\frac{2250}{100}=22.5 \\ \Rightarrow\text{ Tip = 22.5 dollars} \end{gathered}[/tex]Step 2: Add the separate amounts of the tax and tip to the initial bill given to Drian in order to obtain his final bill, as follows:
[tex]Fi\text{nal bill = initial bill + tax + tip}[/tex]Since:
Initital bill = $ 150
Tax = $ 9
Tip = $ 22.5
Therefore:
[tex]\begin{gathered} Fi\text{nal bill = initial bill + tax + tip} \\ Fi\text{nal bill = 150 + 9 + }22.5\text{ = 181.5} \\ \Rightarrow Fi\text{nal bill = }181.5\text{ dollars} \end{gathered}[/tex]Therefore, Drian's final bill is $ 181.5
