Madison and her parents went out to dinner. The total cost of their dinner was \( \$ 38.75 \). They want to leave a tip that is \( 25 \% \) of the total bill. How much tip should they leave? What is total bill including tip?

To determine the appropriate tip and the total bill including the tip, let's break down the problem step by step. ### Given: - **Total Dinner Cost:** \$38.75 - **Desired Tip Percentage:** 25% ### 1. Calculating the Tip To find 25% of the total bill: \[ \text{Tip} = \text{Total Bill} \times \left( \frac{\text{Tip Percentage}}{100} \right) \] Plugging in the numbers: \[ \text{Tip} = 38.75 \times \left( \frac{25}{100} \right) = 38.75 \times 0.25 \] \[ \text{Tip} = 9.6875 \] So, the **tip** should be **\$9.69** (you can round to the nearest cent as appropriate). ### 2. Calculating the Total Bill Including Tip \[ \text{Total Amount} = \text{Original Bill} + \text{Tip} \] \[ \text{Total Amount} = 38.75 + 9.69 = 48.44 \] So, the **total bill including the tip** is **\$48.44**. ### **Summary** - **Tip Amount:** \$9.69 - **Total Bill (Including Tip):** \$48.44
