Jackson is treating his best friend to lunch for his birthday. They order two deluxe hamburgers and fries at $14.95

a plate and two large sodas at $3.49
each. Then as a birthday surprise, Jackson orders two pieces of chocolate cake at $7.95
each. Jackson knows that tax is 8.21%
. How much will Jackson's bill be with tax

The cost of the two deluxe hamburgers and fries is 2 x $14.95 = $<<2*14.95=29.90>>29.90.

The cost of the two large sodas is 2 x $3.49 = $<<2*3.49=6.98>>6.98.
The cost of the two pieces of chocolate cake is 2 x $7.95 = $<<2*7.95=15.90>>15.90.
The total bill before tax is $29.90 + $6.98 + $15.90 = $<<29.90+6.98+15.90=52.78>>52.78.
The tax amount is $52.78 x 8.21/100 = $<<52.78*8.21/100=4.33>>4.33.
Thus, Jackson's bill with tax will be $52.78 + $4.33 = $<<52.78+4.33=57.11>>57.11. Answer: \boxed{57.11}.

To calculate Jackson's bill with tax, we need to find the total cost of the food and beverages first. Let's break it down step by step:

1. Cost of two deluxe hamburgers and fries:
- Each plate costs $14.95.
- Jackson ordered two plates, so the total cost for the hamburgers and fries is: 2 * $14.95 = $29.90.

2. Cost of two large sodas:
- Each soda costs $3.49.
- Jackson ordered two, so the total cost for the sodas is: 2 * $3.49 = $6.98.

3. Cost of two pieces of chocolate cake:
- Each piece of cake costs $7.95.
- Jackson ordered two, so the total cost for the cakes is: 2 * $7.95 = $15.90.

4. Calculate the subtotal:
- Add the costs of the hamburgers and fries, sodas, and cakes: $29.90 + $6.98 + $15.90 = $52.78.

5. Calculate tax:
- The tax rate is 8.21%.
- Multiply the subtotal by the tax rate: $52.78 * 0.0821 = $4.33.

6. Calculate the total bill:
- Add the subtotal and the tax amount: $52.78 + $4.33 = $57.11.

Therefore, Jackson's bill, including tax, will be $57.11.

To calculate Jackson's bill with tax, we need to add up the prices of the hamburgers, fries, sodas, and cakes, and then apply the tax rate.

Let's start by calculating the cost of the hamburgers and fries. According to the given information, each deluxe hamburger and fries plate costs $14.95. Since Jackson ordered two plates, the total cost for the hamburgers and fries would be:

2 plates * $14.95 per plate = $29.90

Next, let's calculate the cost of the sodas. According to the information, each large soda costs $3.49, and Jackson ordered two. So, the total cost of the sodas would be:

2 sodas * $3.49 per soda = $6.98

Now, let's calculate the cost of the chocolate cakes. According to the given information, each piece of cake costs $7.95, and Jackson ordered two pieces. Therefore, the total cost of the cakes would be:

2 cakes * $7.95 per cake = $15.90

Now, let's add up the costs of all the items before tax:

Hamburgers and fries: $29.90
Sodas: $6.98
Cakes: $15.90

Total cost before tax: $29.90 + $6.98 + $15.90 = $52.78

Finally, let's calculate the tax amount. The given tax rate is 8.21%. To find the tax amount, we can multiply the total cost before tax by the tax rate expressed as a decimal:

Tax amount = $52.78 * 0.0821 = $4.34 (rounded to two decimal places)

To calculate Jackson's bill with tax, we need to add the total cost before tax and the calculated tax amount:

Bill with tax = Total cost before tax + Tax amount
= $52.78 + $4.34
= $57.12

Therefore, Jackson's bill with tax will be $57.12.
