Ok, you have to reduce it by 15%, and 15% is the same as 15/100, because you know percentages are out of 100, right? So all you have to do is multiply 20 by 15/100
15 X 20
___
100
300
___
100
= 3
Now you just subtract this from 20
=$17
Alternatively, you could multiply 20 by 85/100 because if you are subtracting 15% of something, this leaves you with 85% of the original thing.
so...
85 X 20
____
100
1700
____
100
=$17
Either way you get the same answer :)

(.15) x $20 = $3.00. So, to reduce $20 by 15%, Subtract the $3.00 from the $20, giving you $17.00. The answer is $17.00.

Easy way to do this -
10% of $20 is $2.00
5% of $20 would be half of the above answer
=$1.00
So, $20. minus $3.00 = $17.00
