You can put this solution on YOUR website!
Per cent means "per one hundred".
In place of "what per cent" I can
put in x%2F100
Now I just read the sentence
$168 is x%2F100 x $560
or
168+=+%28x%2F100%29%2A560
Multiply both sides by 100
16800+=+560x
x+=+30
a commission of $168 on $560
is a commission Of 30 per cent
