You can put this solution on YOUR website!
For some subset within B,

10 may or may not be in the subset (2 choices)
12 may or may not be in the subset (2 choices)
.
.
.
24 may or may not be in the subset. There are eight elements in B, and two choices for each element, so 2%5E8 possible subsets (just think of it as a burger place offering eight different condiments, how many ways to create a burger).
