Answered by PsyDAG
Why not just write 82? It better if you write each score out completely,

Does "7:2 ,5,5,5,8,8,8,8,9" mean 72, 75, 75, 75, 78, 78, 78, 78, 79. If so, count the 78s.

Answer is 4
Reasoning-
because the number in the right section is the tens place while the numbers on the right are the ones place. Therefore using this logic if it says 7:8,8,8,8 that means it’s 4.
