explain your answer
To determine when both shrubs are the same height, we need to find the point where the two lines on the graph intersect. From the graph, we can see that both Magic Grow and Sprout Up have a linear relationship with the height of the shrubs.
The point where the two lines intersect represents the week when both shrubs are the same height. By analyzing the graph, we can see that the intersection point occurs at week 6.
Therefore, the correct answer is C) 6 weeks.
