Answer:
2/3
Step-by-step explanation:
If we divide both 8 and 12 by 4, we would get 2 and 3. 2/3
d $=d*100 cent
Let the unit cost of soda be p cents. So, unit cost of hot dog=2p cents
Total cost=cost of hot dog+cost of soda
or, 100d=h*2p+s*p=p(2h+s)
Or, p=100d(s+2h)p=100d(s+2h)

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
If the lower level has 100 less than 2 times as many seats as the upper level then the expression is 2x-100 and the middle level has 80 more than 3 times as many seats as the upper level so it's 3x+80 and lastly the top level is just x.
so now for the equation you would add all those expressions and they all should equal 2680:
![x+3x+80+2x-100=2680\\6x-20=2680\\6x=2700\\x=450](https://tex.z-dn.net/?f=x%2B3x%2B80%2B2x-100%3D2680%5C%5C6x-20%3D2680%5C%5C6x%3D2700%5C%5Cx%3D450)
but now don't forget to plug in for the middle level:
![3x+80\\3(450)+80\\1350+80\\1430](https://tex.z-dn.net/?f=3x%2B80%5C%5C3%28450%29%2B80%5C%5C1350%2B80%5C%5C1430)
Therefore the middle level has 1430 seats.
