Answer:
$ 17 off
Step-by-step explanation:
20% is one fifth of the price
So divide 85 by 5 you get 17
Since you only get one 1/5 of the price off you save $17
Just to check and make sure you can do 17 * 5 = 85
you should get $68 bc when you take 20% off of 100 you are paying 80% and that in a decimal is 0.8 so you multiply 85 by 0.8
