My Real World Problem

John and five of his friends would like to go to six flags. If the tickets cost $34.99 per person, how much would it cost for john and all of his friends to go?

The Equation

Y= 34.99x or f(x)= 34.99x

X= The number of six flag ticketsY= The total cost

Independent and Dependent

The Independent variable is x which is the number of Six Flags tickets.

The Dependent variable is y which is the total cost.

The total cost depends on the number of Six Flags tickets.

Table of Values

Domain and Range

Domain: is the x valuesRange: is the y values

Domain= {1, 2, 3, 4, 5, 6}Range= {34.99, 69.98, 104.97, 139.96,

174.95, 209.94}

Is it Continuous or Discrete?

My graph is Discrete because my data contains only points and not a line.

Is it a Function?

Yes, it is a Function because the x values don’t repeat.

Conclusion

For John to go to Six Flags by himself it would cost $34.99. But if he went with five of his friends it could cost up to $209.94.
