Here's a question you can shmoop until the cows come home...

00:06

The graph below shows the time (in hours) three students,

00:09

Aaron, Bob, and Chris, spent each day doing homework over a typical school week.

00:17

Apparently, Chris has decided to take over his father's laundry business.

00:22

Based on the graph, which of the following statements is true?

00:24

And here are the potential answers...

00:31

This question really asks a lot of separate questions...

00:34

...so we have to just go through 'em one by one to get to... the promised land.

00:38

So... A. Homework hours. Who studied their buns off and who... didn't?

00:43

We can add the hours across the week for A B and C in this little table:

00:48

A: 2 4 2 4 3 = 15

00:53

B: 3 3 4 5 2 = 17

00:58

C: 4 4 5 3 1 = 17

01:02

Well, Aaron clearly spent the LEAST time on his homework so A is lookin' good.

01:07

But let's check the other statements to be sure we're not... clueless.

01:11

B.

01:12

Bob spent more time on homework than Chris over the entire week. Well... no. They spent

01:16

an equal amount of time.

01:18

C.

01:19

Chris spent the LEAST amount of time on homework -- nope again -- he spent the same as Bob.

01:24

Finally... D.

01:25

Over the week, the 3 students spent an average of 16 hours doing homework.

01:29

Well, we can take an average by totaling the hours -- 15 plus 17 plus 17 gets us 49.

01:36

Their average is 16 and a third -- not 16 so... D is nay as well.

01:41

And A it is.
