Math Is Your Friend, Part 8

, , , , | Right | March 27, 2021

A customer is buying two small boxes, totaling $2.14 with tax. She has a discount card, so I apply that, as well, bringing her total down to $1.84.

Customer: “How much did my discount save me?”

Me: “It looks like it saved you thirty cents.”

Customer: “But what did it save me?”

Me: “It saved you 15% off the boxes, today.”

Customer: “So if I bought more, my total would have been less?”

Me: *Pauses* “No.”

Customer: “Yes!”

Me: “Okay, how?”

Customer: “Because 15% off three, or even four, boxes is more than 15% off only two boxes.”

She gives me a smug look.

Me: “That’s… That’s not how that works. It seems like more of a discount, but only because the dollar amount is also higher.”

Customer: “No! I need four boxes.”

Me: “Okay. With the discount, that’s going to be $3.68.”

Customer: “Wait, no. Why is it more?”

Me: “Because you’re buying more boxes, so you’re spending more money.”

Customer: “Fine. Then I only want two boxes. You just lost a four-box sale!”
