Answer:
$7.92
Step-by-step explanation:
You want to leave a 20% tip on a meal that cost $39.60.
First, convert the 20% 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 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
Second, you need to find out what 20% of your $39.60 meal cost is.This is always done by multiplying 0.20 by $39.60, or 0.20 x $39.60=$7.92.
So, the amount of tip you are going to leave is $7.92.
