Sometimes stores offer multiple discounts – a discount on top of a discount – on an item. Let’s say that Ralph can't sell TVs at 35% off. He tells customers he’ll take another 15% off at the register.
What is the final cost of a $100 TV? You might think it’s 35% off plus 15% off, or 50% off. But that’s not how it works. Here’s what you need to do.
Find the 35% discount first. Then find the first sale price.
First Sale Price:
0.35 × $100 = $35
$100 − $35 = $65
$65 is the new whole. Now take 15% off of that price.
Find the 15% discount of $65. Then find the final sale price.
Final Sale Price:
0.15 × $65 = $9.75
$65 − $9.75 = $55.25
The final sale price for the TV is $55.25.
