Final answer:
An example of a proportional relationship is the relationship between the number of hours worked and the amount of money earned. The constant of proportionality represents the rate at which money is earned per hour worked.
Step-by-step explanation:
An example of a proportional relationship is the relationship between the number of hours worked and the amount of money earned. Let's say that for every hour worked, a person earns $10. This can be represented as:
Money earned = $10/hour x Number of hours worked
In this example, the constant of proportionality is $10/hour. It represents the rate at which money is earned per hour worked.
