How Much Does Your Name Cost?

Here’s a contrived yet fun math problem that I shared with my sons recently:

A local hardware store sells bronze letters. However, the letters vary in price; some are more expensive than others. When I was at the store the other day, four people purchased the letters in their names. Their names and the prices they paid were:

Aiden $491  •  Ned $225  •  Dane $399  •  Ed $135

The price of a name is equal to the sum of the prices of its letters. The price for uppercase and lowercase letters is the same, and there is no additional surcharge or tax. How much would the following people pay to buy the letters in their names?

Edna  •  Ian  •  Nadine

Those of you who know a little algebra will have no trouble with that problem. Those of you who don’t shouldn’t have too much trouble, either.

But then, I realized I could extend the problem for some added fun. And who am I to keep fun things to myself? So, here ya go.

I saw this sign in a window the other day:

Eli - $269

At first, I thought the store was engaging in human trafficking. But then I realized that $269 was the price for the bronze letters that had been used to spell the name Eli. Inside the store was a price list for other names:

AIDEN – 491 AL – 248 ART – 267 BEA – 290
EARL – 415 DANE – 399 ED – 135 ELI – 269
FAY – 220 GABI – 289 HAL – 284 IVY – 143
JACK – 234 JAY – 232 KO – 60 KAI – 283
LEXI – 272 MAVIS – 363 MAX – 215 NED – 225
PAT – 210 PERRI – 330 QI – 93 QUIN – 199
SAMMY – 338 WILL – 243 ZENO – 243

The store didn’t have a list of prices for the individual letters, but then I realized that I didn’t need one. From the table above, I could figure out how much my name  would cost.

Can you figure out how much your name would cost?

You can download both of these problems for use in a classroom (or at a mathy party) from the following link:

And while I don’t believe in answer keys, you can check your work by using the form found on this page.

For what it’s worth, the longest name ever — according to Wolfe + 585, Senior, who has a pretty long name himself — is Rhoshandiatellyneshiaunneveshenk Koyaanisquatsiuth Williams. Her entire name name would have cost $4,073 at this store — an astounding $2,359 for her first name, $1,119 for her middle name, and a veritable bargain at $595 for her tame-by-comparison last name. (Incidentally, this is the name that appeared on her birth certificate. As the story goes, her father later increased her first name to 1,019 letters and added an additional 36 letters to her middle name. You know… just in case the name wasn’t long or unique enough already.)

Decimal Displacement

I used to dislike math, but then I realized that decimals have a point.

For instance, they separate dollars from cents in prices, as shown on the price tag of a Black Brown 1826 shirt that I received as a gift from my mother-in-law:

Shirt Price

Like me, you may be wondering: Why would they include four zeroes instead of just two after the decimal point?

My first thought was that Black Brown 1826 was a London-based company. The tag shows the price in U.S. dollars, so it would make sense that a British company would display the price in U.S. dollars to four decimal places — currency pairs are often expressed to four decimal places.

But that’s not the case. Black Brown 1826 is a clothing line at Lord + Taylor, which is a North American company.

My second thought was that the designer of the line might be European. But nope. The line was designed by Joseph Abboud, an American designer.

My third thought was… well, actually, I didn’t have a third thought. And I still have no idea why the price is expressed to four decimal places.

Do you know why there would be four decimal places shown in the price? If you have a theory, leave a comment.

The location of the decimal point is often a mystery to kids, too, but not for this student…

A math teacher wrote 15.1 on the board. “This is what happens if we multiply by 10,” she said, and then erased the decimal point.

“Now where’s the decimal point?” she asked.

A student answered, “On the eraser!”

But decimal points can also pose problems for adults…

A colleague noticed a new spot on the carpet in the hallway. “Quick! Call the accounting department!” he yelled. “See if they misplaced a decimal point again!”

The Price Is Right

It’s been said that if you have to ask the price of items appearing on a menu without any prices, then chances are you can’t afford to eat at that restaurant.

Million Dollar Bill

The price of tutoring has gotten quite outrageous recently. Some reports claim that SAT tutors are now fetching upwards of $700 per hour, which makes the following guy look like a bargain.

A student was having trouble in math, so his mother decided to hire a tutor. “How much are your sessions?” the mother asked.

“Sixty-five dollars an hour,” the tutor replied.

“That’s quite expensive,” the mother responded. “Is there anything else you can offer?”

“Yes,” said the tutor. “I also offer sessions for $20 an hour… but I don’t recommend them.”

And Lord knows you shouldn’t ask questions that you just don’t want the answer to.

A potential client asked a mathematical consultant, “What are your prices?”

“Four-thousand dollars for three questions,” the consultant replied.

“Four thousand! Isn’t that a bit expensive?”

“Not at all,” replied the consultant. “Now, what’s your third question?”
