If n is an integer and 101n^2 is less than or equal to 6400, what is the greatest possible value of n?
Pick: A) 7 B) 8 C) 9 D) 10 E) 11

Rationale: 101 * n ^ 2 < = 6400 n ^ 2 < = 6400 / 101 which will be less than 81 since 6400 / 100 = 64 which is the square of 9 next closest value of n where n ^ 2 < = 64 is 7 ans a
Answer: A
