Roger can read a book in k minutes. What part of the book can he read in 7 minutes? (k>8)
Pick:  A) 8+k  B) k/8  C) 7/k  D) (k+ 8)/k  E) (k-8) / k
Let's sayk = 24   That is, it takes 24 minutes to read the entire book.   So, in 8 minutes, Roger can read1/3of the book   So, we're looking for the answer choice that yields an OUTPUT of1/3whenk = 24   A) 8+24=32ELIMINATE   B) 8/24=1/3KEEP   7/k)24/8 =3ELIMINATE   D) (24+ 8)/24=32/24 = 4/3ELIMINATE   E) (24-8) /24=16/24 = 2/3ELIMINATE   Answer: 7/k
