Hello! Please help me, my school year ends this friday and I need to finish this in order to get course credit!!
Question: Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.

Sure, here are two scenarios:
Scenario 1: The cost of a meal at a restaurant.
Data pairs:
| Number of people | Cost of meal |
| ---------------- | ------------ |
| 1 | $10 |
| 2 | $20 |
| 3 | $30 |
| 4 | $40 |
Scenario 2: The time it takes to complete a task with varying levels of effort.
Data pairs:
| Effort level | Time to complete task |
| ------------ | --------------------- |
| 2 hours | 10 minutes |
| 3 hours | 8 minutes |
| 5 hours | 6 minutes |
| 8 hours | 4 minutes |
It is up to your classmates to determine which scenario is a direct variation (where y=kx) and which scenario is an inverse variation (where y=k/x) and calculate the value of k for each.
