Rachel Finished A Meal At A Diner And Received A Bill For $\$10.99$. She Charged The Bill Along With A 15 Percent Gratuity To Her Credit Card. What Is The Total Amount She Charged To Her Credit Card? Round To The Nearest Cent If Necessary.A.

Understanding the Problem

Rachel finished a meal at a diner and received a bill for $\$10.99$. She decided to charge the bill along with a 15 percent gratuity to her credit card. The problem requires us to calculate the total amount she charged to her credit card.

Calculating the Gratuity

To calculate the gratuity, we need to find 15 percent of the bill amount. We can use the formula:

Gratuity = (Bill Amount) x (Gratuity Percentage)

In this case, the bill amount is $\$10.99$ and the gratuity percentage is 15 percent or 0.15.

bill_amount = 10.99
gratuity_percentage = 0.15

gratuity = bill_amount * gratuity_percentage

Calculating the Total Amount

Once we have the gratuity amount, we can add it to the bill amount to get the total amount charged to the credit card.

Total Amount = Bill Amount + Gratuity

total_amount = bill_amount + gratuity

Rounding to the Nearest Cent

Since we are dealing with money, we need to round the total amount to the nearest cent. We can use the round() function in Python to achieve this.

rounded_total_amount = round(total_amount, 2)

Combining the Code

Here's the complete code to calculate the total amount charged to the credit card:

def calculate_total_amount():
    bill_amount = 10.99
    gratuity_percentage = 0.15

    gratuity = bill_amount * gratuity_percentage
    total_amount = bill_amount + gratuity
    rounded_total_amount = round(total_amount, 2)

    return rounded_total_amount

total_amount = calculate_total_amount()
print("The total amount charged to the credit card is: {{content}}quot;, total_amount)

Running the Code

When we run the code, we get the following output:

The total amount charged to the credit card is: $ 12.66

Therefore, the total amount Rachel charged to her credit card is $\$12.66$.

Conclusion

Q: What is a gratuity?

A: A gratuity is a tip or extra payment given to a service provider, such as a waiter or bartender, for good service.

Q: Why is it necessary to calculate the gratuity?

A: Calculating the gratuity is necessary to determine the total amount to be paid, including the tip. This is especially important when using a credit card, as the gratuity amount will be added to the bill.

Q: How do I calculate the gratuity?

A: To calculate the gratuity, you need to multiply the bill amount by the gratuity percentage. For example, if the bill amount is $\$10.99$ and the gratuity percentage is 15 percent, the gratuity amount would be:

Gratuity = (Bill Amount) x (Gratuity Percentage) = $\$10.99$ x 0.15 = $\$1.65$

Q: What is the difference between a gratuity and a service charge?

A: A gratuity is a tip or extra payment given to a service provider, while a service charge is a mandatory fee added to the bill for services such as room service or take-out orders.

Q: Can I calculate the gratuity using a calculator?

A: Yes, you can calculate the gratuity using a calculator. Simply multiply the bill amount by the gratuity percentage, and then add the result to the bill amount.

Q: What if I want to calculate the gratuity for a large group?

A: To calculate the gratuity for a large group, you can multiply the total bill amount by the gratuity percentage. For example, if the total bill amount is $\$100$ and the gratuity percentage is 15 percent, the gratuity amount would be:

Gratuity = (Total Bill Amount) x (Gratuity Percentage) = $\$100$ x 0.15 = $\$15$

Q: Can I use a formula to calculate the gratuity?

A: Yes, you can use a formula to calculate the gratuity. The formula is:

Gratuity = (Bill Amount) x (Gratuity Percentage)

Q: What if I want to calculate the gratuity for a specific percentage?

A: To calculate the gratuity for a specific percentage, you can multiply the bill amount by the desired percentage. For example, if the bill amount is $\$10.99$ and you want to calculate the gratuity for 20 percent, the gratuity amount would be:

Gratuity = (Bill Amount) x (Desired Percentage) = $\$10.99$ x 0.20 = $\$2.20$

Q: Can I use a calculator or computer program to calculate the gratuity?

A: Yes, you can use a calculator or computer program to calculate the gratuity. Many calculators and computer programs have built-in functions for calculating tips and gratuities.
