Answer: $57.60
Step-by-step explanation: The formula for discount price is:
72-(72*.20) = 57.60
However you can factor out the 72:
72(1.0-0.20)=57.60 the answer would then just be 72(.80) = 57.60
If you need to do it quickly just think "if i took 20% off of 100% i'm left with 80% so this item costs 80% of the regular price"
