Answers for December "Fun with Math"

Ten winners for "planetary costs" puzzlers

Ten kids got all three answers correct in the December "Fun with Math" puzzler concerning the costs of things on three imaginary planets.

FM creator George Yu asked for you to figure out what things cost on three different planets. And the costs were to be figured out based on clues determined from characteristics of the words.

The costs weren't in dollars and cents.

That sounds a little confusing but quite a number of you figured out the various relationships.

There were 10 kids who got all correct answers.

To determine who should get the three $10 Borders gift certificates, all 10 names were put in a hat and three were drawn out.

Those getting the gift certificates this month were: Malik Hadjri, of St. Louis; Natasha Meinzen of Edwardsville, IL, and Jacob Veitch of Edwardsville.

Others who got all answers correct were:

John Bentley of Edwardsville; Monica Chaven of Edwardsville; Quentin Crane of Edwardsville; Michael Kim of St. Louis; Danielle Kirsch of Edwardsville; Durga Kullakanda of Maryland Heights, and Chad Turner of Glen Carbon, IL.

Solution for December's
Fun with Math

  1. "Book" has four letters, "apple" has five letters, and "sharpie" has seven letters. Each item costs four times the number of letters it has. "Handshake" has nine letters so it costs
    9x4 = 36 coins.

  2. "Kazoo" has three vowels and two consonants. "Basket" has two vowels and four consonants. "Treasure" has four vowels and four consonants. If we let v be vowels and c be consonants, we have
    3v+2c = 19
    2v+4c = 26
    4v+4c = 32
    From these equations we find that a vowel costs three pieces of paper and a consonant costs five pieces of paper. "Ukulele" has four vowels and three consonants so it costs
    4x3+3x5 = 27 pieces of paper.

    The number of pieces of paper that each item costs is the number of letters times six. The number of coins each item costs is the difference between the number of vowels and consonants. "Peace" costs 5x6 = 30 pieces of paper
    and 3-2 = 1 coin.
