A $20 item is 50% off. What is the sale price?

How to work it out

1. 1

   The original price is $20 and the discount is 50%.

2. 2

   Method 1: find the discount, then subtract it.

   $$50\% \text{ of } 20 = 0.5 \times 20 = 10\qquad 20 - 10 = 10$$
3. 3

   Method 2: you pay 50% of the price, so multiply by 0.5:

   $$20 \times 0.5 = 10$$
4. 4

   Answer: the sale price is $10 and you save $10.
