Question

Caroline goes out to lunch. The bill before tax and tip was $10.95. A sales tax of 8% was added. Caroline tipped 13% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip?

Answer 1

To find the total cost of Caroline's meal including tax and tip, calculate the sales tax of 8% and add it to the original bill, then calculate a 13% tip on the new amount and add that to get a total of $13.37.

Step-by-step explanation:

First, calculate the sales tax by converting the percentage to a decimal and multiplying it by the initial bill amount. The sales tax is 8% of $10.95, which is calculated by:

0.08 × $10.95 = $0.876. This amount is then added to the original bill, giving us a sub-total:

$10.95 + $0.876 = $11.826.

Next, calculate the tip, which is 13% of the amount after adding the sales tax. Convert 13% to a decimal and multiply by the sub-total:

0.13 × $11.826 = $1.53738, which we can round to $1.54 for simplicity.

Finally, add the tip to the sub-total to get the total cost of the meal:

$11.826 + $1.54 = $13.366, rounded to the nearest cent is $13.37.

Therefore, Caroline's total cost for the meal after tax and tip is $13.37.
