Answer:

\$4140

Step-by-step explanation:

According to the problem, <em>x </em>refers to teams, and N(x)=x^{2}-x represents numbers of games played.

So, if there are 10 teams, we just have to replace this value for the <em>x</em> and calculate the number of games. Once we have it, we multiply all games by $46, which is the cost per game.

N(x)=x^{2} -x\\N(10)=(10)^{2}-10=100-10=90

This means that in the entire schedule there are 90 games. If each one costs $46, the whole schedule will cost:

90(\$46)=\$4140
