Answer:
Option (c) is correct.
Average expense is given by function [tex]C(x)=\frac{\$11+\$1x}{x}[/tex]
Step-by-step explanation:
Given : The family arcade center charges an entry fee of 11$ plus an additional $1 per game played.
We have to choose from the given options a function that describes the average expense for a player per game played.
Let x be the number of game played.
So, The entry fee will be same for all that is $ 11
And in addition $1 is charged per game played.
when they play x games the charge will be $1 × x = $ x
Thus,
Average expense is defined as the total charge divided by number of player per game played.
That is Total charge per person = $ 11+ $1x
Since, there are x game played.
Thus, Average expense is given by function
[tex]C(x)=\frac{\$11+\$1x}{x}[/tex]
