Answer: $30.40
Step-by-step explanation: If you know that the original price is $38 and it was marked down by 20%, you could multiply the original price by ".80". This represents 80% of the original cost, since it was marked down by 20%. By multiplying $38 by .80, you end up with $30.40.
Hope this helps!
