Answer:
The answer is 9.2
Step-by-step explanation:
Total number paintings made by 7 children = [tex]7\times8=56[/tex]
Total number of paintings made by the remaining 3 children (10-7) = [tex]3\times12=36[/tex]
Therefore, total number of paintings = [tex]56+36=92[/tex]
Hence, average number of paintings by all the 10 children =
[tex]\frac{92}{10}[/tex] = 9.2
So, the average number of paintings made by children at the art camp is 9.2.
