You want to leave a 18% tip on a meal that cost $150.
First, convert the 18% 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 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.
Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or
0.18 x $150.00=$27.00.
So, the amount of tip you are going to leave is $27.00.
This makes the total cost of your meal (to write on your charge slip or other payment)
$150.00 + $27.00 = $177.00.
