a. 9
b. 60
c. 15
d. 25

Answer 1

I think you multiply the different ways of getting from school to the library and the library to home

Answer 2

For every route from school to the library,
she can choose 5 routes going home.

with 3 routes from school to the library,
she'll have 3 • 5 = 15 routes from the school to her home.

Answer 3

Using the figure below, how many "paths" can you make between the school and her home?



This represents the number of routes possible.

Once you understand the process, you can simply multiply 3 and 5 to get the same answer.
