Willem bought a jacket on sale. the price was 40% off the original price of $60.how much did he pay?

40% off the original price means that Willem paid 100% - 40% = 60% of the original price.
So 60% of $60 = (60/100)$60 = 0.6 * $60 = $36.
He paid $36.
Inbox me in case you need more explanation

First, we have to figure out what percentage of the price Willem is going to pay. 

Since it is 40% OFF, he will have to pay 60% if the price.  
60% in decimal form is 0.6.  To get 60% of 60, multiply 60 by 0.6.  60 * 0.6 = 36.  

So, Willem will pay 36$ for the jacket when it's on sale.  

I hope this helps! Can I have Brainliest, please? :)
