Answer:
x = -3
In-Depth Steps:
1.) Start with the bottom equation: 
2.) Set 
alone on one side of the equal sign. Your equation will look like 
.
3.) Plug 
in for in the first equation. You will get 
.
4.) Distribute. Your equation now looks like this: 
.
5.) Combine like terms. You will get 
.
6.) Subtract 6 from both sides. You get 
. We can learn that Y=0.
7.) Go back to either equation and put 0 in for y.
8.) In the top equation, it would look like 
and the bottom equation would look like 
. We basically got our answer of 
, but we will plug it into the equation, and in-fact, we get x = -3.
Answer:
$85
Step-by-step explanation:
5000 x $70 = $350,000
4950 x $71 = $351,450
4900 x $72 = $352,800
etc.
Create an equation for the monthly revenue:
f(n) = (5000 - 50n) x (70 + n)
= 350000 + 5000n - 3500n - 50n²
= 350000 + 1500n - 50n²
where n is the amount the ticket price is increased from $70.
Differentiate, equal to zero and solve for n to find the value of n when the monthly revenue is at its maximum:
f'(n) = 1500 - 100n
1500 - 100n = 0
1500 = 100n
15 = n
Therefore, the maximum monthly revenue is when n = 15.
So the cost of the ticket will be 70 + n = 70 + 15 = 85
