Answer:

the skater needs to get a score of 97  [or more ]

Step-by-step explanation:

[ 83 + 88 + 92  + M  ] / 4   ≥  90      multiply both sides by  4

 

83 + 88 + 92  + M ≥   360     simplify

 

263 + M ≥ 360           subtract  263 from both sides

 

M ≥  97      →  the skater needs to get a score of 97  [or more ]

Answer:97

Step-by-step explanation:

83+88+92+97=360

360/4=90
