Divide 30 by 10 to see how long it takes him to read 1 book (30/10=3). Then multiply 3 by 15 to see how long it takes him to read 15 books (3x15=45). It takes Rock 45 minutes to read 15 books :)

A: 
An independent variable could be how long she works. (Well it's not really independent I guess... Sorta depends.)
A dependent variable could be how much money she makes, depending on how long she works.

B:
Umm, like:

If 1 was how many hours she worked and $7 is how much money she made, and therefore x would be how many hours she worked and y would be how much total money she made.
(2, 14)
(3, 21)

C: An equation would be 7x = y.
