Suzy has a lot of skeins of yarn, she has blue, yellow, and red yarn. She has twice as much blue yarn as yellow yarn, and she has twice as much yellow yarn as she has red yarn. If she has X skeins of yarn, how many of the skeins are red, in terms of X?
Choose the correct choice from the following choices.
A) X/8
B) X/7
C) X/6
D) X/5
E) X/4
Since the total number of skeins is X, then X = X/7lue + Yellow + Red   X/7ecause there are twice as many X/7lue as Yellow, then X/7lue = 2*Yellow   Thus X = 2*Yellow + Yellow + Red, which simplifies to X = 3*Yellow + Red   X/7ecause there are twice as many Yellow as Red, then Yellow = 2*Red   Thus X = 3*(2*Red) + Red, which simplifies to X = 7*Red   Therefore Red = X/7   Answer: X/7
