A telecommunications company determines that the data overage fee ($y$) varies directly with the number of gigabytes used ($x$) over the limit. If a customer is charged $20 for 8 GB of overage, the constant of variation ($k$) in the equation $y = kx$ is ____.

A project manager is analyzing a direct variation relationship where a team's total output ($y$) varies directly with the hours worked ($x$). Using the data that 8 hours of work produced 20 units of output, match each step of finding the direct variation equation to its correct mathematical expression.

An HR manager determines that the total budget for employee training ($y$) varies directly with the number of participants ($x$). If the budget is $20,000 for 8 participants, the direct variation equation that relates the budget (in thousands of dollars) to the number of participants is $y = 2.5x$.

A billing specialist at a consulting firm determines that the total service fee ($y$) varies directly with the number of hours ($x$) spent on a project. If a project is billed $20 for 8 hours of work, which equation represents the correct initial substitution of these values into the direct variation formula $y = kx$ to find the constant of variation?

A project manager determines that the total cost of equipment kits ($y$) varies directly with the number of kits ordered ($x$). If 8 kits cost $20, resulting in the model $y = 2.5x$, match each mathematical component to its specific role in this professional scenario.
