In this question, the markdown is the amount the screwdriver was reduced, in dollars and cents. So, it is really asking what is 20% of $40. Solve this by 0.2*40=8. So the markdown is $8. If the question asked what the final price would be, take the original price and subtract the markdown, 40-8=$32.
Hope this helps.
