Remember that $130 microwave discounted by 40%? To determine the sale price, we calculated the discount by taking 40% of $130 and subtracting this amount from the original price.
Here's a quicker way to calculate the final price.
If the price is discounted 40%, this means you must pay 60% of the original price (100% – 40% = 60%). So, calculate 60% of $130 (.60 × $130) and you've got a sale price of about $80.
