Total number of units = q
Cost of each unit = 100/q + 7
Total cost of q units = q(100/q +7) = 100+7q
To make revenues greater than $8,000
8000<100 +7q
8000-100 < 7q
7900<7q
q>7900/7
q>1128.58
q>1129 units
Therefore, the minimum number of units sold must be greater than 1129 units.
Answer: The cost of adult ticket is $6.1 and that of student ticket is $2.44
<u>Step-by-step explanation:</u>
Let the cost of adult ticket be 'x' and cost of student ticket be 'y'
From the question, the equations formed are:
.....(1)
......(2)
Putting value of 'y' from equation 2 to equation 1:
![662.5=85(2.5x)+65y\\\\662.5=271.5y\\\\y=\frac{662.5}{271.5}=\$ 2.44](https://tex.z-dn.net/?f=662.5%3D85%282.5x%29%2B65y%5C%5C%5C%5C662.5%3D271.5y%5C%5C%5C%5Cy%3D%5Cfrac%7B662.5%7D%7B271.5%7D%3D%5C%24%202.44)
Now, solving for 'x', we get:
![x=2.5(2.44)=\$ 6.1](https://tex.z-dn.net/?f=x%3D2.5%282.44%29%3D%5C%24%206.1)
Hence, the cost of adult ticket is $6.1 and that of student ticket is $2.44
C is the correct graph because u can't get a cubed root of a negative number
if u chose 8 to bring x the cubed root is 2 and 2 - 3 = -1...graph matches
