I think the right answer is A.
7.5 / .45 = 16.666, or 16 max folders per drawer
100 is 6 drawers of 16 folders with 4 left over, 4*.45 = 1.8
I am sure there is a quicker way to a solution, assuming my answer is even correct, but maybe this will help you somehow

- if each drawer can only hold 7.5 inches of the folders, 7.5/0.45 = 16.6666. round this down to 16 because you can’t place 0.67 of a folder in a drawer. from this you know that each drawer can take 16 folders
- to find how many drawers will be completely filled, 100/16 = 6.25. this means 0.25 of the last drawer will be filled.
- from step 1 you learned that each drawer can fill 16 folders. 0.25*16 = 4. the last drawer will have 4 folders.
- each folder is 0.45 inches thick. 0.45*4 = 1.8. the combined thickness of the partially filled drawer is 1.8 inches.
