Verified step by step guidance

1. Identify the total lunch bill amount, which is \$17.65, and the tip percentage, which is 18\%.
2. Convert the tip percentage from a percent to a decimal by dividing by 100: \$18\% = \frac{18}{100} = 0.18$.
3. Set up the expression to find the tip amount by multiplying the total bill by the decimal tip rate: \(\text{Tip} = 17.65 \times 0.18\).
4. Perform the multiplication to calculate the tip amount (do not calculate the final value here, just set up the expression).
5. The result from the multiplication will give the amount of the tip Saphia should leave.
