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)
$$
Step 1: Calculate the sales tax amount.
To find the sales tax amount, multiply the food cost by the sales tax rate:
105.79 * 9% = $<<105.79*9*.01=9.52>>9.52
Step 2: Calculate the pre-tax amount.
To find the pre-tax amount, subtract the sales tax amount from the total cost:
105.79 - 9.52 = $<<105.79-9.52=96.27>>96.27
Step 3: Calculate the tip amount.
To find the tip amount, multiply the pre-tax amount by 20%:
96.27 * 20% = $<<96.27*20*.01=19.25>>19.25
Step 4: Calculate the total cost, including tax and tip.
To find the total cost, add the food cost, sales tax amount, and tip amount:
105.79 + 9.52 + 19.25 = $<<105.79+9.52+19.25=134.56>>134.56
The total cost, including tax and tip, will be $134.56.
