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

Which of the methods can you use to find the sale price?

Question 2: Which best describes why one of the methods that can be used to find the sale price would be easier to use than the others?

"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.

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.
