Jake got the following scores in the first 5 quizzes: 11, 9, 13, 18, 17.
What score must Jake get in the next test for him to get an average of 14?
~~~~~~~~~~~~~~~~~~ 

    %2811%2B9%2B13%2B18%2B17%2Bx%29%2F6 = 14

    11 + 9 + 13 + 18 + 17 + x = 14*6

             68 + x           =  84

                  x           =  84 - 68 = 16.
