I worked admissions for a popular tourist attraction in Hollywood. A guest hands me a coupon: $8 OFF PER TICKET.
Me: “Your total is $44.”
Guest: “You forgot to include the coupon.”
Me: “I included the coupon. Ticket is $30—” *I point to the sign next to me.* “—so for the two of you that’s sixty, minus eight, and minus eight again is $44.”
Guest: “Did you include the coupon?”
Me: “I included the coupon. $30 per ticket. Two tickets are sixty dollars, minus $8, and minus $8 is $44.”
Guest: “Sixteen.”
Me: “Right. I took sixteen off.”
Guest: “No, ticket price is sixteen dollars.”
Me: “No, it’s $22 with the coupon.”
Guest: “How much is the regular ticket price?”
Me: “$30.”
Guest: “Coupon is for how much?”
Me: “Eight dollars off.”
Guest: “Right. So that brings the price down to sixteen.”
Me: “Um… no, it doesn’t.”
Guest: “Thirty dollars minus eight dollars, right?”
Me: “Yes.”
Guest: “Sixteen.”
Me: “No. $22.”
Guest: “Forget it. What’s my total?”
Me: “$44.”
Guest: “Did you include the coupon this time?”
Me: “Yes.”
Guest: “How does it come to $44?”
Me: “Ticket price is $30. You gave me a coupon for eight dollars off, which brings the price down to twen—”
Guest: “—Sixteen.”
Me: “—TWENTY-TWO. There are two of you. Two tickets come to $44.”
Guest: “Did you include the coupon?”
Me: “Yes.”
Guest: “How much is the ticket?”
Me: “$30.”
Guest: “What about the coupon?”
Me: “Coupon brings it down to $22.”
Guest: “Not $16?”
Me: “Not $16.”
Guest: “Why not $16?”
Me: “Because that’s not what math is!”
Guest: “Are you sure?”
I pulled out a piece of paper and drew thirty little lines, crossed out eight, and asked him to count.
