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)
$115.31
$126.95
$136.47
$138.37
The sales tax on the food will be 9% of $105.79, which is 0.09*105.79 = <<0.09*105.79=9.50>>9.50
The pre-tax amount is $105.79, so the tip will be 20% of $105.79, which is 0.20*105.79 = <<0.20*105.79=21.16>>21.16
The total cost will be the cost of the food ($105.79) plus the tax ($9.50) plus the tip ($21.16), which is 105.79+9.50+21.16 = <<105.79+9.5+21.16=136.45>>136.45.
The closest answer choice is $136.47, so the correct answer is $136.47. Answer: \boxed{136.37}.
