Jesse buys his coworkers lunch from the local steakhouse. The food cost $105.79 in 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 sales tax amount is $105.79 * 9% = $<<105.79*9*.01=9.522099999999999>>9.52.
The pre-tax amount is $105.79 - $9.52 = $<<105.79-9.52=96.27>>96.27.
The tip amount is $96.27 * 20% = $<<96.27*20*.01=19.254>>19.254.
The total amount is $105.79 + $9.52 + $19.254 = $<<105.79+9.52+19.254=134.56400000000002>>134.56. Answer: \boxed{134.56}.
To calculate the total including tax and tip, you need to follow these steps:
Step 1: Calculate the sales tax amount.
Sales tax rate = 9%
Food cost = $105.79
Tax amount = Food cost * (sales tax rate / 100)
Tax amount = 105.79 * (9 / 100)
Tax amount = $9.52
Step 2: Calculate the pre-tax amount.
Pre-tax amount = Food cost - Tax amount
Pre-tax amount = 105.79 - 9.52
Pre-tax amount = $96.27
Step 3: Calculate the tip amount.
Tip rate = 20%
Tip amount = Pre-tax amount * (tip rate / 100)
Tip amount = 96.27 * (20 / 100)
Tip amount = $19.25
Step 4: Calculate the total amount.
Total amount = Pre-tax amount + Tax amount + Tip amount
Total amount = 96.27 + 9.52 + 19.25
Total amount = $125.04
Therefore, the total amount, including tax and tip, will be $125.04.
To calculate the total, including tax and tip, you'll need to follow these steps:
Step 1: Calculate the sales tax amount.
The sales tax rate is given as 9%, so you need to find 9% of the food cost. To do this, multiply the food cost by 9% (or 0.09):
Sales tax amount = $105.79 * 0.09 = $9.52 (approximately)
Step 2: Calculate the pre-tax amount.
To get the pre-tax amount, subtract the sales tax amount from the food cost:
Pre-tax amount = $105.79 - $9.52 = $96.27 (approximately)
Step 3: Calculate the tip amount.
Jesse wants to leave a 20% tip based on the pre-tax amount. To find the tip amount, multiply the pre-tax amount by 20% (or 0.20):
Tip amount = $96.27 * 0.20 = $19.25 (approximately)
Step 4: Calculate the total amount.
Finally, to find the total amount including tax and tip, add the pre-tax amount, sales tax amount, and tip amount:
Total amount = Pre-tax amount + Sales tax amount + Tip amount
Total amount = $96.27 + $9.52 + $19.25 = $124.04 (approximately)
Therefore, the total amount, including tax and tip, will be approximately $124.04.
