Answer:
The break- even point is attained when n=75
Step-by-step explanation:
The break-even point is defined as the point where revenue is equal to cost.
We take the equation for revenue r=15n, and set it equal to the equation c=9n+450
15n=9n+450
Subtract 9n from both sides:
6n=450
Divide both sides by 6.
6n/6=450/6
n=75
The break- even point is attained when n=75....
Answer:
Number of Rides:
Number of Games: 
Step-by-step explanation:
Given
Represent the games with G and the Rides with R
-- cost
--- cost
-- cost
Required
Represent the system using an equation
The equation can be represented as follows;

Assume She plays G games and had R rides, we have

Since she plays twice as much games as rides,
This implies;

So, we have


--- This equation can be used to solve for Number of Rides
Solving further


Substitute 3 for R in 


Solve for 1.5G

--- This equation can be used to solve for Number of Games
