If @ is a binary operation defined as the difference between an integer n and the product of n and 5, then what is the largest positive integer n such that the outcome of the binary operation of n is less than 14?  Select the correct option
A) 1  B) 2  C) 3  D) 4  E) 5
@(n) = 5n - n   We need to find the largest positive integer such that 5n - n &lt; 14.   Then 4n &lt; 14 and n &lt; 3.5.   The largest possible integer is n = 3.   The answer is 3.
