Introduction

In this discussion, we will explore the relationship between the number of piano lessons given by Blake in an evening and the amount he earns. We will analyze the given information and determine the range of this relation.

Given Information

  • Blake gives piano lessons in the evenings.
  • He earns $20 for each piano lesson.
  • He has between 0 and 6 lessons each evening.

Understanding the Relationship

Let's denote the number of piano lessons given by Blake in an evening as 'x' and the amount he earns as 'y'. We know that Blake earns $20 for each piano lesson, so the amount he earns is directly proportional to the number of lessons he gives. This can be represented by the equation:

y = 20x

Range of the Relation

To find the range of this relation, we need to determine the possible values of 'y' for the given values of 'x'. Since Blake has between 0 and 6 lessons each evening, the possible values of 'x' are:

0, 1, 2, 3, 4, 5, 6

We can substitute these values into the equation y = 20x to find the corresponding values of 'y':

  • For x = 0, y = 20(0) = 0
  • For x = 1, y = 20(1) = 20
  • For x = 2, y = 20(2) = 40
  • For x = 3, y = 20(3) = 60
  • For x = 4, y = 20(4) = 80
  • For x = 5, y = 20(5) = 100
  • For x = 6, y = 20(6) = 120

Conclusion

The range of this relation is the set of all possible values of 'y' for the given values of 'x'. In this case, the range is:

{0, 20, 40, 60, 80, 100, 120}

This means that the amount Blake earns in an evening can be any value between $0 and $120, depending on the number of piano lessons he gives.

Graphical Representation

The relation between the number of piano lessons and the amount earned can be represented graphically as a straight line with a slope of 20. The x-axis represents the number of lessons, and the y-axis represents the amount earned.

Mathematical Representation

The relation can be represented mathematically as a linear equation:

y = 20x

This equation represents the direct proportionality between the number of piano lessons and the amount earned.

Real-World Applications

This type of relation is commonly found in real-world scenarios, such as:

  • Sales commissions: A salesperson earns a commission for each sale made, and the amount earned is directly proportional to the number of sales.
  • Production costs: A manufacturer earns a profit for each unit produced, and the amount earned is directly proportional to the number of units produced.

Conclusion
