Here’s an unshmoopy question that may haunt you on some future exam…

00:07

The following graph shows how many different vehicle models of an automaker fall into the

00:11

different categories for fuel efficiency. 

00:14

How many models are rated for more than 35 miles per gallon?

00:18

And here are the potential answers...

00:24

Can we read a table?

00:26

The question asks for MORE THAN 35 miles per gallon – this is like Prius territory plus

00:32

so we ignore the 31-35 bar and everything to its left.

00:37

The “more than” group is the last 2 bars. The 36-40 bar is 5 models if you draw a straight

00:45

line across the top to the y axis.

00:49

Do the same on the 41-45 group and it looks like 2 models – so 5 plus 2 is 7.

00:56

And our answer is B.
