Answer 1

Hello!

First, let's calculate the tax rate and the amount of the tips. Then, we'll add these values to the total bill.

Tax Rate: 8.25%

$\begin{gathered} \frac{87}{x}=\frac{100\%}{8.25\%} \\ \\ 100x=87\times8.25 \\ 100x=717.75 \\ x=\frac{717.75}{100} \\ x=7.1775\cong7.18 \end{gathered}$

Tips: 15%

$\begin{gathered} \frac{87}{x}=\frac{100\%}{15\%} \\ \\ 100x=87\times15 \\ 100x=1305 \\ x=\frac{1305}{100} \\ \\ x=13.05 \end{gathered}$

Total bill:

$87+7.18+13.05=\ 107.23$
