Problem 35
Question
Including \(8 \%\) sales tax, an inn charges \(\$ 162\) per night. Find the inn's nightly cost before the tax is added.
Step-by-Step Solution
Verified Answer
The nightly cost before tax is approximately $150.
1Step 1: Understand the percentages
We have the total amount that includes 8% tax. This means, the final price is 108% of the initial price. Let's denote the initial price (the price before tax) as \(P\). Then, we can say that \(108\% \) of \(P\) equals $162.
2Step 2: Setting up the equation
Based on the relation established in the previous step, set up the equation: \(1.08 \cdot P = 162\), where 1.08 is the numerical value of 108% (since 1 corresponds to 100% and 0.08 corresponds to 8%).
3Step 3: Solving for P
To find \(P\) (the initial price), divide both sides of the equation by 1.08: \(P = 162/1.08\). Calculate this to find the value of \(P\).
