Let the number of adults be x, then number of male students is 1 + 7x and the number of female students is (1 + 7x)/2.
x + 1 + 7x + (1 + 7x)/2 = 82
2x + 2 + 14x + 1 + 7x = 164
23x = 164 - 2 - 1 = 161
x = 161/23 = 7
Therefore, number of male students is 1 + 7(7) = 1 + 49 = 50
and the number of female students is 50/2 = 25.
This was rough, but either way I love math haha

Based on the total number of pages in the textbook, and the total thickness, the average thickness per page is 0.0047 cm.
<h3>What is the average thickness per page?</h3>
The average thickness per page of the textbook can be found by the formula:
= Total thickness of textbook / Number of pages
Solving gives:
= 3.86 / 820
= 0.0047 cm
In conclusion, the average thickness per page is 0.00470 cm.
