Answer:
Step-by-step explanation:
1) First take the price of the item, let's say it is $10, and multiply it by 0.7. This will give you the price of the item AFTER the sale price is already taken off.
$10 x 0.7 = $7
2) Another way is to multiply the price by 0.3. Take that number and subtract it from the full price to get your discounted price.
$10 x 0.3 = $3
$10 - $3 = $7
