To find the percent. A trick I learned in middle school was Dr. P
To turn a decimal to a percent and a percent to decimal... (look at picture)
Using that trick...
All you do is multiply $287.69 by .20
Which gives you $57.538 so you can round to either...
$57.54
Or
$57.50
Or
$58
And one of those are your answer!
