Mrs. Durbin, Mrs. Johnson, and Mrs. Specter, whose first names are Darla, Hannah, and Mabel, though not necessarily in this order, went shopping for bargains after Christmas.

While shopping, Mabel spent twice as much as Hannah and Hannah spent three times as much as Darla.

If Mrs. Durbin spent $3.85 more than Mrs. Specter, what is each lady's full name and how much did they each spend?
