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 ____.

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.
