Answer:
15 tenth graders
Explanation:
we can see that dogs take up 1/2 of the graph
birds take up 1/2 of 1/2 so they take up 1/4
other and cats together take up 1/4 of the graph which is 1/8 for each
you must add dogs and cats together and then multiply it bu 24
1/2 + 1/8
4/8 + 1/8 = 5/8
now multiply that by 24
24 * 5/8
that is the answer
