1.- 260 - 110 = 150 children
2.- 150 X $2.50 (rate of children) = $375

x = 120*25/12
x=250
Answer 250 girsl
A point doesn't have slope. Once you have TWO points, then the line between them has a slope.
The slope is (how far the line rises from one point to the other) divided by (the level distance between them).
I think the answer is 2.25 or 2 and 1/4.
You divide 3/4 by 1/3 and get 2.25 or 2 and 1/4.
I don't know if this is right, I hope it is, have a good day. c;
