Final answer:
To calculate an 18% tip on a $27.65 bill, the tip is found to be approximately $4.98 and the total amount Carson will leave is $32.63.
Step-by-step explanation:
Carson went to lunch with his grandmother and the total bill was $27.65. He wants to leave an 18% tip. To calculate the tip, first convert the percentage to a decimal by dividing by 100, which gives 0.18. Then multiply the bill amount by 0.18 to find the tip amount:
Tip = 0.18 × $27.65
Tip = $4.977 or approximately $4.98 when rounded to the nearest cent.
Now, add the tip to the original bill to find the total amount Carson will leave:
Total amount = Original Bill + Tip
Total amount = $27.65 + $4.98
Total amount = $32.63
This is the amount Carson will leave for the total bill and tip.
