Your coach can select it 4 times I think
You have to do 91/13 which is 7 which means that each hen lays 7 eggs per week so the unit rate is 7
Her average score for the 3 turns is 40 because you have to add all of the scores so -80 and -120 is -200 so add that to 320 and you get 120 divide that by 3 because she took 3 turns and you get 40
