Dave and Sarah are going bowling with Mike and Nikki. Mountain Lanes charges $1.50 per player per game and $2.00 for a shoe rental. Valley Lanes charges $2.50 per game but offers a free shoe rental. Assuming that each bowler must rent shoes, which lane offers the better deal for one game of bowling? Does your answer change for 2 games? 3? 4?
Let "x" be the number of games and "y" represent the cost. Graph your results. Write an equation that describes each situation.
($1.50/game, $2 shoe rental)
|1) Which line
is steeper? What does this mean in the context of the problem?
2) Where does each line intersect with the y-axis? What is this point called? What does this point mean in the context of the problem?
3) How would this problem have changed if Mountain Lanes also charged $2.50 per game?
