Answer:
3.5 dollars
Step-by-step explanation:
The price of one comic book is 3.5.
I got this by dividing 21 and 6

Because the area is the length*width, to find the width, we must divide the area by the length.
Think of it this way:

Divide l on both sides:

And w is what we're looking for.
So, divide 159 3/8 by 18 3/4.
You should get that the width is 8.5 feet :)
