Yep.

Answer 7

thank you! how would I try solving b?

Answer 8

24-13?

Answer 9

Hof these 24, how many are boys? girls?

Answer 10

Or I guess that would answer C

Answer 11

13 boys went on the trip

Answer 12

We have to figure out how many girls went on the trip also

Answer 13

Yes, and how many girls went along?

Answer 14

I would say 11. Because if 24 students went, and 13 of them were boys, than 24-13=11
