Answer:
D
Step-by-step explanation:
If C represents the number of children you aren't gonna want to multiple like how it shows in option b and you aren't gonna wanna subtract.
I think that's what your looking for
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28
This can be factored/simplified by dividing everything by 7
=7(m - 4)
Hope this helps! :)
