1. **State the problem:** Fabian's dinner bill was 35 dollars, and he wants to leave a 15% tip. We need to find the total amount he will pay including the tip, before tax. 2. **Calculate the tip amount:** The tip is 15% of 35 dollars. $$\text{Tip} = 0.15 \times 35 = 5.25$$ 3. **Calculate the total amount:** Add the tip to the original bill. $$\text{Total} = 35 + 5.25 = 40.25$$ 4. **Final answer:** Fabian's meal plus the tip, before tax, is **40.25 dollars**.
