Jesse buys his coworkers lunch from the local steakhouse. The food cost $105 point $.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.
The food cost is $105.79.
The sales tax rate is 9%, so the tax amount will be 9% of $105.79, which is $9.52.
The pre-tax amount is $105.79, so the 20% tip will be 20% of $105.79, which is $21.16.
Adding the food cost, tax amount, and tip amount together, the total cost will be $105.79 + $9.52 + $21.16 = $<<105.79+9.52+21.16=136.47>>136.47.
Therefore, the total cost including tax and tip will be $136.47.
