Evaluate the following numerical expression. int number; int x = 9, y = 5; float ave = 13.5 number = ( x + y / 3 * 2 ) + ave / x -1 * ave;

Correct Answer
-1

Explanation
number = (x+y / 3*2) + ave / x - 1 * ave;
number = (9+5 / 3*2) + 13.5 / 9 - 1 * 13.5;
number = (9+1*2) + 1.5 - 1 * 13.5;
number = (9+2) + 1.5 - 13.5;
number = (11) - 12.0;
number = - 1.0;
number = -1;

- C.
  
  It is fine.
Correct Answer
B. The m needs to have ‘’ around it ‘M’.
