If x and y are integers, what is the least positive number of 24x+16y?
Choose the correct choice from the following answers.
A) 3 B) 4 C) 5 D) 6 E) 8
24x+16y = 8(3x+2y) which will be a minimum positive number when 3x+2y = 1.   3(1) + 2(-1) = 1   Then 8(3x+2y) can have a minimum positive value of 8.   The answer is 8.
