Elena-2011 [213]

Answer:

It will cost $700 to play the entire​ schedule.

Step-by-step explanation:

Given : N(x)=x^2-x

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

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

N(x)=20

So, The total no. of games = 20

Cost for 1 game = $35

So, cost for 20 games = 35 \times 20 = 700

Hence  it will cost $700 to play the entire​ schedule.
