# Dueling Discounts

### 20% off vs $20 off By Ricardo Garcia

## Arguement

Looking at the desk (example 2), we have a price of $99.99. Which most of us would round to $100. On first glance $20 might seem like the better deal to most. But doing the math we see in this example both coupons hold the same value. 20% of 100 is 20. Take that $20 and minus it from the $100 and we get $80. Same with the $20 off coupon, $20 minus $100 is $80. So in some cases the amount of the item itself is the key, not the coupon itself.

The big screen T.V. (example 3), has a price of $1499.99. Again to make it easier for us we would round to an even $1500. In this case which coupon to use is at first glance harder to figure out in our heads without stepping back and thinking about it. So what does the math say? Easiest one is the $20 off coupon. $1500 minus $20 is $1480. Not a very impressive discount. Using the the 20% off coupon, the math says we can save $300. A far more impressive discount. $1500 minus $300 is $1200. 20% off wins in this scenario.

## What if we had coupons of 5% off and $5 off?

Using the same examples but with different values for the discounts, lets see if there is any change. In the case of the Batmobile 5% off would give a discount of $1.35. Still less of a discount of then $5 off coupon. So in this scenario there is no change.

Looking at the desk, 5% off would get you a discount of $5. Which is equal to the discount offered by the $5 off coupon. Once again no change even with different values.

For the t.v. 5% off gives a total savings of $75. Still far greater a discount the the $5 off coupon.
