MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's edition of the Friday Update!

Playing Cards
Margaret and her friends are playing a card game. In a deck of 36 solid colored cards, each card is purple, blue or green. There are twice as many blue cards as purple cards and the number of green cards is equal to half of the combined number of purple and blue cards. How many cards are green?
--------------------------------------------------------------------------------
The deck of 36 cards from the previous question is shuffled and turned face down. What is the probability that Margaret draws a blue card?
--------------------------------------------------------------------------------
From the 36 card deck mentioned above, 4 blue cards are removed. The remaining cards are shuffled and turned face down. What is the probability that Margaret draws a purple card from the deck?

Answer to last week’s MATHCOUNTS problem:
Each A is worth 4 points, so:
4 points × 3 classes = 12 points

Each B is worth 3 points, so:
3 points × 2 classes = 6 points

Find Stanley’s average by dividing the total number of points by the number of classes he took.

12 + 6 = 18

18 ÷ 5 = 3.6
--------------------------------------------------------------------------------
Use quizzes, which are worth the least, as the basic unit…

Each test is equal to 2 quizzes; therefore, 3 tests are equivalent to 6 quizzes.
Each project is equal to 1.5 tests; therefore, 2 projects are equal to 3 tests, which is equal to 6 quizzes.

Since each group of assignments (3 tests, 6 quizzes, 2 projects) is equal to the same amount of your grade, each group of assignments is equal to 1/3 of her grade.

There are 2 projects, so:

½ × 1/3 = 1/6

Each project is worth 1/6 of her grade.
--------------------------------------------------------------------------------
First you need to find the sum of the 4 quiz scores. To do this, use the average “equation.”

x ÷ 4 = 89 points

x = 356 points

Now find the sum of the three remaining quiz scores.

x ÷ 3 = 94 points

x = 282 points

The difference between the two sums is the score that was dropped.

356 – 282 = 74 points
