Laser tag is one of the coolest games ever, so you want to spend your Saturday playing it as much as you can. Each round at a local laser tag arena costs $3 to play, but if you buy a daily pass for $10, you can play games for just $1 a round. You only have enough time to play 10 games at most, but you want to find out if it would be more cost effective to buy the pass or to just pay the $3 per game. Write or graph two functions (this means you should be using function notation) to show how much money you would spend depending on how many games you play. ​
