According to the Original Tipping Page, www. tipping.org, it is appropriate to tip waiters and waitresses \( 15 \%-20 \% \) of the pre-tax restaurant bill. The Leeseburgs' dinner costs \( \$ 40.25 \) before tax, and the tax rate is \( 4 \% \). a) What is the tax on the Leeseburgs' dinner? b) If the Leeseburgs decide to tip \( 17 \% \) of the pre-tax bill, how much is the tip? c) What is the total cost of the dinner including the tax and tip?

To solve this problem step by step: a) To find the tax on the Leeseburgs' dinner, we multiply the pre-tax bill by the tax rate. The tax is calculated as: \[ \text{Tax} = \$40.25 \times 0.04 = \$1.61 \] b) To calculate the tip based on a \( 17\% \) tip rate on the pre-tax bill: \[ \text{Tip} = \$40.25 \times 0.17 = \$6.84 \] c) Now, to find the total cost of the dinner including the tax and tip: \[ \text{Total Cost} = \text{Pre-tax Bill} + \text{Tax} + \text{Tip} \] \[ \text{Total Cost} = \$40.25 + \$1.61 + \$6.84 = \$48.70 \] So the total cost of the dinner including the tax and tip is \( \$48.70 \).
