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)

Answer 1

The sales tax on the food will be 9% of $105.79, or $105.79 * 0.09 = $<<105.79*0.09=9.5311>>9.5311.
The total bill before tip will be $105.79 + $9.5311 = $<<105.79+9.5311=115.3211>>115.3211.
The tip amount will be 20% of $105.79, or $105.79 * 0.2 = $<<105.79*0.2=21.158>>21.158.
The final total, including tax and tip, will be $115.3211 + $21.158 = $<<115.3211+21.158=136.4791>>136.4791. Answer: \boxed{136.4791}.
