Question 554993
I live close to the local water park. I would like to go to the park throughout the summer but Im wondering what type of pass to purchase for the better deal. I have 2 options when it comes to purchasing a pass to the park. I can either buy an annual pass for $100.00 that can be used as many times as I would like throughout the summer or I can purchase a daily pass each time for $25.00. Depending on the amount of times I visit the park will depend on what would be the best to buy. I plan to visit the park at least 7 times.
I need to create algebraic equations that represent the cost/yield and then I have to graph them.
:
The annual pass: y = 100 (Red)
The single pass: y = 25x
:
The graph: y axis is cost, x axis is no. of visits
{{{ graph( 300, 200, -6, 10, -50, 220, 100, 25x) }}} 
Obviously, if you visit 7 times, the annual would be best.
