Answer: Let's call the number of games that Lorelel plays "x".
The cost of playing x games would be:
4.25x
In addition to the cost of playing, Lorelel also has to pay a shoe rental fee of $9.59, regardless of how many games she plays.
So the total cost, C, of playing x games and renting shoes would be:
C = 4.25x + 9.59
For example, if Lorelel plays 3 games, the cost would be:
C = 4.25(3) + 9.59 = 21.34
If Lorelel plays 6 games, the cost would be:
C = 4.25(6) + 9.59 = 35.09
And so on, for any number of games she chooses to play.
