Can some help plzz I am stuck on this math problem!!

Answer:
60 points in 5 games
Step-by-step explanation:
plug the numbers of points scored into the top boxes, so the boxes should look like ( [8]+[11]+[12]+[16]+[n] ) then plug in the number of games he played in the bottom box [5] so 8+11+12+16+n all divided by 5 has to = 12
5x12 = 60
n= 60-8-11-12-16 n= 13
