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?

Question

$__

Answer 1

First, we need to calculate the pre-tax amount of the food.

Food cost = $105.79
Sales tax rate = 9%

Tax amount = Food cost * Sales tax rate
Tax amount = $105.79 * 0.09
Tax amount = $9.53

Pre-tax amount = Food cost - Tax amount
Pre-tax amount = $105.79 - $9.53
Pre-tax amount = $96.26

Next, we need to calculate the tip based on the pre-tax amount.

Tip rate = 20%
Tip amount = Pre-tax amount * Tip rate
Tip amount = $96.26 * 0.20
Tip amount = $19.25

Now, we can calculate the total cost including tax and tip.

Total cost = Food cost + Tax amount + Tip amount
Total cost = $105.79 + $9.53 + $19.25
Total cost = $134.57

Therefore, the total cost, including tax and tip, will be $134.57.
