original price -.90 * original price = sales price

OR

we know that 90 percent off = 10 percent of

original price * .10 =sales price


The second method is easier because it is less complicated math.  

"The scooter is on sale for 90% off the original price. "

90% off meaning the sale price is 1 - 90% = 10% of the original price.

another way is to calculate what 90% of the originial price is; then subtract that from the original price (because its 90% OFF.)


1st method is easier to use because 10% of original price is simply shifting the decimal to the left by one position.
