Answered by Steve
I'd start with the biggest book:

200 = 100+100
200 = 100+50+50
200 = 100+50+10+10+10+10+10

and so on, breaking each possible book down into its parts. Watch out for duplicate entries.
Answered by Ms. Sue
2 books of 100
4 books of 50
1 book of 100 and 2 books of 50
20 books of 10

How many more combinations can you find?

Answered by PsyDAG
This should give you a start.

100 + 100
100 + (50 * 2)
100 + 50 + 20 + 20 + 10
100 + 50 + 20 + 10 +10 +10…

20 * 10…

10 * 20.
