Answer:
It will cost $700 to play the entire schedule.
Explanation:
Given :
![N(x)=x^2-x](https://img.qammunity.org/2020/formulas/mathematics/college/koftngwxqh7wd4f5jpt8i1ri6lpb68d5dh.png)
To Find : A softball league has 5 teams, each of which play the others twice. If the league pays $35 per game, how much will it cost to play the entire schedule?
Solution:
Equation for total no. of games when all the teams play each other twice is
![N(x)=x^2-x](https://img.qammunity.org/2020/formulas/mathematics/college/koftngwxqh7wd4f5jpt8i1ri6lpb68d5dh.png)
Now we are given that A softball league has 5 teams, each of which play the others twice.
So, Substitute x = 5 in the given equation
![N(x)=5^2-5](https://img.qammunity.org/2020/formulas/mathematics/college/un8i9e8gdlhho1ztavt84fr9f1n3tbkvjz.png)
![N(x)=20](https://img.qammunity.org/2020/formulas/mathematics/college/eknbchlfasbkbxicqvyx73dbto9xzmlb9c.png)
So, The total no. of games = 20
Cost for 1 game = $35
So, cost for 20 games =
![35 * 20 = 700](https://img.qammunity.org/2020/formulas/mathematics/college/hy16r7d5dac1hi11rh0gu7wqxjimue7l4c.png)
Hence it will cost $700 to play the entire schedule.
