Coupon % vs $

Use a coupon worth
$20 off your entire purchase
OR
20% off your entire purchase?

h/t @ddmeyer

Whichever option you choose, justify your reasoning with mathematics.

As a follow-up to this, there could be a conversation around when it would be worth it to take the 20% coupon. What if it was a 30% coupon? Where is the breaking point?

To extend this even further as a full lesson around percent markup and discount, Dan has done some extensive work on the lesson design.

    I would rather have 20 dollars taken off of my purchase. I think this because if you think about it 20% is only one fifth and a example of me taking 20% off 1.00 its only a discount of 20 cents. Another example 20% off of 50 dollars it will only be 10 dollars off and it would be 40. But , if you take 20 off it would be 20.
