Answer :
Using linear functions, it is found that you need to rent 5 games for the costs of the servers to be the same.
What is a linear function?
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the membership fee as the intercept and the cost per game as the slope, the functions are:
- A(x) = 7x + 25.
- B(x) = 12x.
The costs are the same when:
B(x) = A(x)
12x = 7x + 25
5x = 25
x = 5.
Hence you need to rent 5 games for the costs of the servers to be the same.
