Hi

first is 16 points more than the second and sum of the three scores is 217  

Let (x+16), x, (217 - (2x +16) represent the 1st,2nd and 3rd scores respectively

Question states***

(x+16) + x = 2[(217 - (2x +16] +28

solving for x

  2x + 16 = -4x + 402 + 28

      6x = 414

       x = 69, the second score, first is 85   (69+16)



CHECKING our Answer***Note 3rd score is 63  (217-69-85)

   69 + 85 = 2*63 + 28 = 154
