Final answer:
The equation Y = 0.5X could represent a situation where X represents the number of hours worked and Y represents the amount of money earned, such as an employee's salary.
Step-by-step explanation:
In the equation Y = 0.5X, X and Y are variables representing quantities.
A situation that could be represented by this equation is an employee's salary.
Let's say X represents the number of hours worked in a week and Y represents the amount of money earned.
If an employee earns $20 per hour, the equation Y = 0.5X can be used to calculate their weekly earnings.
