Answer:
He played 7 arcade games.
Step-by-step explanation:
The amount paid in relation to the number of games played can be modeled by a linear function in the following format:
![A(n) = F + gn](https://tex.z-dn.net/?f=A%28n%29%20%3D%20F%20%2B%20gn)
In which F is the flat rate and g is the price of each game.
Flat fee of $30 but he had to pay $2 for each arcade game he played.
This means that ![F = 30, g = 2](https://tex.z-dn.net/?f=F%20%3D%2030%2C%20g%20%3D%202)
So
![A(n) = 30 + 2n](https://tex.z-dn.net/?f=A%28n%29%20%3D%2030%20%2B%202n)
Jason spent $44. How many arcade games did he play?
This is n for which A(n) = 44. So
![A(n) = 30 + 2n](https://tex.z-dn.net/?f=A%28n%29%20%3D%2030%20%2B%202n)
![44 = 30 + 2n](https://tex.z-dn.net/?f=44%20%3D%2030%20%2B%202n)
![2n = 14](https://tex.z-dn.net/?f=2n%20%3D%2014)
![n = \frac{14}{2}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B14%7D%7B2%7D)
![n = 7](https://tex.z-dn.net/?f=n%20%3D%207)
He played 7 arcade games.
