Answer: There isn't a possible way you can really answer this question because I don't know how much one piece cost in the first place , but if I had to guess I would say around 50-80 dollars for a cake is enough for 57 guests.
explanation: I say this because I know usually cakes for a decent amount of people are around 50-80 dollars.

Answer:
F means function and F(x) means function of x
Step-by-step explanation:
375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased
Step-by-step explanation:
Let x be the number lower reserved tickets
and
y be the number of upper reserved tickets
Then according to given statements
![x+y = 740\ \ \ \ Eqn\ 1\\9.50x+8y = 6482.50\ \ \ \ Eqn\ 2](https://tex.z-dn.net/?f=x%2By%20%3D%20740%5C%20%5C%20%5C%20%5C%20Eqn%5C%201%5C%5C9.50x%2B8y%20%3D%206482.50%5C%20%5C%20%5C%20%5C%20Eqn%5C%202)
From equation 1:
![x = 740-y](https://tex.z-dn.net/?f=x%20%3D%20740-y)
Putting in equation 2
![9.5(740-y)+8y = 6482.50\\7030-9.5y+8y = 6482.50\\7030-1.5y = 6482.50](https://tex.z-dn.net/?f=9.5%28740-y%29%2B8y%20%3D%206482.50%5C%5C7030-9.5y%2B8y%20%3D%206482.50%5C%5C7030-1.5y%20%3D%206482.50)
Subtracting 7030 from both sides
![7030-7030-1.5y = 6482.50-7030\\-1.5y=-547.5](https://tex.z-dn.net/?f=7030-7030-1.5y%20%3D%206482.50-7030%5C%5C-1.5y%3D-547.5)
Dividing both sides by -1.5
![\frac{-1.5y}{-1.5} = \frac{-547.5}{-1.5}\\y = 365](https://tex.z-dn.net/?f=%5Cfrac%7B-1.5y%7D%7B-1.5%7D%20%3D%20%5Cfrac%7B-547.5%7D%7B-1.5%7D%5C%5Cy%20%3D%20365)
Putting y = 365 in equation 1
![x+365 = 740\\x = 740 - 365\\x = 375](https://tex.z-dn.net/?f=x%2B365%20%3D%20740%5C%5Cx%20%3D%20740%20-%20365%5C%5Cx%20%3D%20375)
Hence,
375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased
