1. **State the problem:** Skylar got a manicure for 28 and a pedicure for 35. She plans to tip 15%. We need to find the total amount she will pay including the tip. 2. **Formula:** Total cost including tip is given by $$\text{Total} = \text{Cost} + \text{Tip} = \text{Cost} \times (1 + \text{Tip rate})$$ 3. **Calculate the total cost before tip:** $$28 + 35 = 63$$ 4. **Calculate the tip amount:** $$\text{Tip} = 63 \times 0.15 = 9.45$$ 5. **Calculate the total amount to pay:** $$\text{Total} = 63 + 9.45 = 72.45$$ 6. **Answer:** Skylar will pay a total of 72.45 including the tip.
