The cost of a skateboard is $60. it went on sale and is now 33% off. what is the amount of the skateboard now?
Law Incorporation [45]
To find the answer for this question, you need to convert your percent to a fraction. (33/100) You will multiply 60 by 33/100, and get 19.8. That shows you the discount you are getting. Finally, you need to subtract 19.8 from 60, getting you a final answer of $40.2.
