Writing and Graphing a Direct Variation Equation

Creative Scenarios

Scenario 1: Cameron works at a local grocery store after school. He is paid $8 for each hour he works.

Scenario 2: At a local bakery, one box of donuts costs $5. Two boxes of donuts cost $10.

Consider the two scenarios given above. Can you write an equation to represent each situation? What would the graphs of these equations look like? Can you think of a situation that would result in a similar equation?

Describe a scenario that would result in an equation similar to the equations for Scenarios 1 and 2. Post your scenario and the corresponding equation to the discussions area. Then, return to the topic several times over the next few days to read your coursemates’ posts. “Vote” for the three scenarios that you think are most creative by replying to each with the word “like” and writing at least one sentence explaining why you like it. The scenario with the most “likes” and an appropriate equation is the class favorite.
