Question

Your lunch cost $12.50.  do you want to tip 20%.  what is your total. 

Answer 1

To calculate the total cost including a 20% tip for a $12.50 lunch, convert the percentage to a decimal, multiply it by the cost of the lunch to find the tip amount, and then add the original cost of the lunch and the tip amount together.

Step-by-step explanation:

To find the total amount including a 20% tip, you need to calculate the amount of the tip first. The tip amount is found by converting the percentage to a decimal and then multiplying it by the original cost of the lunch. In this case, 20% as a decimal is 0.20. Multiplying this by $12.50 gives you a tip amount of $2.50.

Next, you add the original cost of the lunch and the tip amount to find the total. Adding $12.50 and $2.50 gives you a total of $15.00. So, your total cost, including the 20% tip, is $15.00.
