Askateboard that sells for $65 is on sale for 15% off. find the sale price?

The skateboard now sells for 55.25. Hope this helps.

Original price:          $65        
discount:         15% off        
sale price:         ?        

There are two ways you can solve this problem:

Here's the longer way (by one step):
65 * .15 (15% in decimal form) = 9.75
65 - 9.75 = 55.25
sale price = $55.25

Here's the method that's one step shorter:
65 * .85 (100-15 ~ because it's 15%[15/100] off) = 55.25
sale price = $55.25

Either way works for solving discounts/sales.
