Answer 21

Ok

Answer 22

In your previous question, A was the correct answer:
this is more of a pattern analysis than anything
notice that per every 10 years, the price maintains its pattern of decreasing/increasing
at the end of 2010, it is completing a downfall
come 2020, given the previous years trends, one might expect it to go back up
to around it's max average, which is about 600.

Answer 23

I'll wait on Miacrown before I close

Answer 24

I knew it! Thanks!

Answer 25

we can also consider our other choices
480 670 and 430 the two on bottom 430 and 480 don't comply with the upward trend that would be expected to occur by upward trend, i mean increase in price during this 10 year span and the 670 choice is an increase yet it is somewhat unrealistically high
considering that the max price point is relatively consistent around this 600 figure.
