To find the total bill with tax, we will follow these steps:
- Calculate the cost of the food items without tax.
- Apply the tax rate.
- Sum these amounts to get the final total.
Step 1: Calculate the cost of food items.
-
Cost of two deluxe hamburgers and fries: \[ 2 \times 14.95 = 29.90 \]
-
Cost of two large sodas: \[ 2 \times 3.49 = 6.98 \]
-
Cost of two pieces of chocolate cake: \[ 2 \times 7.95 = 15.90 \]
Now, add these together: \[ 29.90 + 6.98 + 15.90 = 52.78 \]
Step 2: Calculate the tax.
Calculate the tax amount: \[ \text{Tax} = 52.78 \times 0.0821 \approx 4.33 \]
Step 3: Calculate the total bill with tax.
Add the tax to the cost of the food: \[ 52.78 + 4.33 = 57.11 \]
Therefore, Jackson's bill with tax is $57.11.
