Ooh, scary math
n+2b=67.5
n=27
27+2b=67.5
minus 27 both sides
2b=40.50
divide both sides by 2
b=20.25

Answer:
8 or 9
Step-by-step explanation:
So, you first need to take 4/5 of 400 (320). Then, you can count by 75s for a bit
75students; 2chaperones
150; 4
225; 6
300; 8
now, you have 20 students left over...since one chaperone would watch about 37 kids, you can either divide the remaining kids up among the other chaperones, or you can add one more chaperone to watch the 20 kids. i don't know what the teacher wants, so either 8 or 9 chaperones
first get all variables on the same side, then use elimination to solve.
x = -3
y = -11
Perhaps you could just outline the topic lightly but try your best not to give away your topic idea. In this case talk about technology but don't talk about the dependency of technology, for the first paragraph as mentioned in your title text and then in your second paragraph you could talk about the dependency of technology.
