To calculate the total cost of your restaurant outing, let's break it down step-by-step:
-
Calculate the cost of the food items:
- Appetizer: $9.99
- Entrées: 2 x $7.99 = $15.98
- Dessert: $3.49
Total cost of food items: \[ 9.99 + 15.98 + 3.49 = 29.46 \]
-
Calculate the sales tax:
- Sales tax rate: 6%
- Sales tax amount: \[ 29.46 \times 0.06 = 1.7676 \text{ (rounded to 1.77)} \]
-
Calculate the cost including tax: \[ 29.46 + 1.77 = 31.23 \]
-
Calculate the tip:
- Tip rate: 15%
- Tip amount: \[ 31.23 \times 0.15 = 4.6845 \text{ (rounded to 4.68)} \]
-
Calculate the total cost: \[ 31.23 + 4.68 = 35.91 \]
So, the total cost of your restaurant outing is $35.91.
Correct Response: $35.91
