4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
I honestly don't know any of this so

Thank you
Step-by-step explanation:
Answer:
Given: 175 g/L
1 gram/liter = 0.06242796 pound/cubic foot
175 g/L * 0.06242796 pound/cubic foot= 10.924893 lb/ft3
So, a foam material has a density of 10.924893 lb/ft3 in units of lb/ft3
