Solve the problem.Recycling, like all real processes, is not 100% efficient. Each time an aluminum can is recycled, a portion of the can becomes unrecoverable and thus "disappears" from future recycles. The fraction of an aluminum can that is reclaimable after n recycles is given by F = (0.87)n. The can has effectively "disappeared" when F < 0.07. How many times can the can be recycled before it "disappears"?

A. 22 B. 17 C. 21 D. 19
