Skate Outing Cost Calculation for Friends

Mariah and Natasha are planning to go skating with three friends, and tickets cost $5.00 each. To calculate the total cost for all five, we use the equation y = 5.00x, where x is the number of tickets and y is the total cost. The independent variable x represents the number of tickets (1 to 5), while the dependent variable y denotes the total cost ($5.00 to $25.00). This scenario illustrates a discrete function, as x values do not repeat, confirming it is a function. The total cost for all friends is $25.00, excluding food and drinks.

  1. Function Project Alysha Green

  2. Real World Problem Mariah and Natasha are going skating with three other friends. If tickets cost $5.00 a piece, then how much will it cost for all of them to go.

  3. The Equation y= 5.00x or f(x)= 5.00x x= The number of skating tickets y= The total cost

  4. Independent and Dependent The independent variable is x, the number of skating tickets. The dependent variable is y, the total cost. Since y depends on x, the total cost depends on the number of skating tickets.

  5. Table of Values

  6. Domain and Range The domain is D:{1,2,3,4,5} The range is R:{5.00,10.00,15.00,20.00,25.00}

  7. Is it Continuous or Discrete? It is discrete, because it only contains points.

  8. Is this a Function? Yes, because my x values do not repeat. Do NOT repeat

  9. Graph

  10. In conclusion... It would cost Mariah, Natasha, and there three other friends $25.00 all together, without extra drinks or food. +
