A little birdie told us you wanted a shmoopy problem to solve... and we shall provide.
- 00:08
Included below in Figure 1 are some salary statistics by year from Major League Baseball.

Basically, it just wants to know if we can interpret what it means when those bars in
- 00:28
the graph keep getting bigger and bigger...
- 00:31
Okay, so based on the graph, what do we know about the average player
- 00:35
salaries and the minimum wage?
- 00:37
Are they increasing, decreasing, or staying the same?
- 00:40
Well, they're definitely not staying the same. Otherwise, all of the bars would be
- 00:43
the same height.
- 00:45
The bars are getting taller year after year, so we can cross off option D.
- 00:49
Now let's check out the legend, or key of the graph.

AVERAGE wage is getting higher, not the minimum wage.
- 01:12
Next, the red part of the graph. Is it getting higher over time?
- 01:17
Yup, the red part is definitely increasing. So option B is our answer.
- 01:21
Both the average wage and the minimum wage increase over time.
- 01:25
And good thing, too. Considering how bad inflation is.
