Sally eats lunch at a restaurant and her bill is $12. She would like to leave a 15% tip for the waiter. How much money should she leave?

Hope this helps!

Step-by-step explanation:

Answer -Full amonut - $13.80. Tip amount - $1.80

First, convert the 15% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $12 meal cost is. This is always done by multiplying 0.15 by $12.00, or
