Math Problem Statement

The cost of a particular private school begins with a​ one-time initiation fee of ​$20002000​, plus annual tuition of ​$6 comma 0006,000. This situation can be modeled by a linear function. Identify the independent and dependent variables. Draw a graph of the​ function, then use the graph to find the cost to attend this school for 44 years. Is a linear model reasonable for this​ situation? Question content area bottom left Part 1 The number of years is the ▼ independent dependent variable. The cost is the ▼ independent dependent variable.

Solution

The graph shows the total cost of attending the private school over time. For 4 years of attendance, the total cost is $26,000.

Is a linear model reasonable?

Yes, a linear model is reasonable in this case because the cost increases by a fixed amount ($6,000) each year, which is characteristic of a linear relationship. The one-time initiation fee adds a constant to the cost, but it doesn't affect the linearity of the model over time.

Would you like more details on this or have any other questions? Here are 5 related questions you might find helpful:

  1. How would the function change if the initiation fee were higher or lower?
  2. What if there were a yearly increase in tuition of a fixed percentage?
  3. How would the total cost change if the student attended for 10 years?
  4. How can you calculate the break-even point between two schools with different tuition costs?
  5. How would the graph change if there were a yearly discount applied after 5 years?

Tip: Linear models are best suited for situations where changes are consistent over time, such as a constant yearly fee or rate.
