Answer:
1. ![C=21x.](https://tex.z-dn.net/?f=C%3D21x.)
2. ![C=(8x+104).](https://tex.z-dn.net/?f=C%3D%288x%2B104%29.)
Step-by-step explanation:
Let the number of people in the group be x. Denote the total cost as C.
1. If the regular cost is $21 per person, then the total regular cost for x people is ![C=21x.](https://tex.z-dn.net/?f=C%3D21x.)
2. If the special cost is $8 per person, then the total special cost for x people is
There is an additional $104 fee for a private room, thus the total special cost is ![C=(8x+104).](https://tex.z-dn.net/?f=C%3D%288x%2B104%29.)

Answer:
z = 42
Step-by-step explanation:
The question can be answered in 2 steps as follows:
Step 1: Calculation of the constant of the variation
The equation for the joint variation can be given as follows:
z = cxy ................... (1)
Where;
z = 60
c = constant = ?
x = 5
y = 6
Substituting the values into equation (1) and solve c, we have:
60 = c * 5 * 6
60 = c * 30
c = 60 / 30
c = 2
Step 2: find z when x = 7 and y = 3
Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:
z = 2 * 7 * 3
z = 42
