Jesse buys his coworkers lunch from the local steakhouse. The food costs $105.79, and the sales tax rate is 9%. Jesse wants to leave a 20% tip based on the pre-tax amount. How much will the total be, including tax and tip?(1 point)

Question

$

Answer 1

To calculate the total amount Jesse will spend, we need to break it down into three parts: the pre-tax amount, the sales tax, and the tip.

1. Pre-tax amount: $105.79
2. Sales tax: 9% of the pre-tax amount \[ \text{Sales Tax} = 0.09 \times 105.79 = 9.4781 \approx 9.48 \]
3. Total after tax: \[ \text{Total after Tax} = \text{Pre-tax amount} + \text{Sales Tax} = 105.79 + 9.48 = 115.27 \]
4. Tip: 20% of the pre-tax amount \[ \text{Tip} = 0.20 \times 105.79 = 21.158 \approx 21.16 \]
5. Total amount including tax and tip: \[ \text{Total} = \text{Total after Tax} + \text{Tip} = 115.27 + 21.16 = 136.43 \]

Therefore, the total amount will be $136.43.
