A board of length L feet is cut into two pieces such that the length of piece A is 4 feet less than three times the length of piece B. Which of the following is the length, in feet, of piece A?  Answers:
A) (L+4)/3	B) (L-4)/4	C) (3L-4)/4	D) (3L-1)/3	E) (3L+4)/4
A+B = L so we know that B = L - A.   A = 3B-4   A = 3(L-A) - 4   4A = 3L - 4   A = (3L-4) / 4   The answer is (3L-4)/4.
