Explanation:

Part A

Step 1: Calculate the tax amount

The tax rate is 8%, and the cost of food and beverages is $25.30. To find the tax amount, we calculate 8% of $25.30.
The formula for calculating a percentage of a number is: \( \text{Tax Amount} = \text{Cost} \times \text{Tax Rate} \)
So, \( \text{Tax Amount} = 25.30 \times 0.08 \)
\( 25.30 \times 0.08 = 2.024 \)

Step 2: Calculate the total bill

The total bill is the cost of food and beverages plus the tax amount.
\( \text{Total Bill} = 25.30 + 2.024 \)
\( 25.30 + 2.024 = 27.324 \approx 27.32 \) (rounded to the nearest cent)

Step 1: Use the total bill from Part A

From Part A, the total bill (including tax) is $27.32.

Step 2: Calculate the tip amount

The tip rate is 18%. To find the tip amount, we calculate 18% of $27.32.
The formula for calculating a percentage of a number is: \( \text{Tip Amount} = \text{Total Bill (with tax)} \times \text{Tip Rate} \)
So, \( \text{Tip Amount} = 27.32 \times 0.18 \)
\( 27.32 \times 0.18 = 4.9176 \)

Step 3: Calculate the total cost including tip

The total cost is the total bill (with tax) plus the tip amount.
\( \text{Total Cost} = 27.32 + 4.9176 \)
\( 27.32 + 4.9176 = 32.2376 \approx 32.24 \) (rounded to the nearest cent)

Answer:

\( \$27.32 \)
