Answer: (C)

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 calculate the tip by multiplying the total bill by the decimal tip rate: \(\text{Tip} = 17.65 \times 0.18\).
4. Perform the multiplication to find 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 Saphia should leave as a tip.
