Chicago is the green line, so where the green line first crosses above the red line (phoenix).

OpenStudy (agent0smith):

It's asking when Chicago first exceeds phoenix, so when the green line (representing Chicago) first crosses above the red line (representing phoenix).

OpenStudy (anonymous):

OpenStudy (agent0smith):

OpenStudy (agent0smith):

See where the pink line hits the vertical axis? That's about where the answer is. Where would you guess it hits it?

OpenStudy (agent0smith):

I extended the green line to show January, the pink line is just to estimate how high it is

OpenStudy (anonymous):

so its 98?

OpenStudy (agent0smith):

Correct!

OpenStudy (anonymous):

lol heres another one

OpenStudy (agent0smith):

I'm guessing that they should improve motor quality. The graph shows their production costs are dropping, which probably means they're cutting costs, and producing poor quality motors which break within the 3 year warranty.

OpenStudy (agent0smith):

Notice the production costs are dropping, while the warranty costs are increasing... they're related. Poor production = poor quality motors.
