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
0.15 x $12.00=$1.80.
So, the amount of tip you are going to leave is $1.80. full amount - 13.80
