Assignment:
Sarah was an artist who made sets of etched dry-point prints. She first created each printing plate in the set by using a sharp instrument to scratch an artistic image onto the plate's hard surface. It took an average of one hour to prepare the design on the surface. She made a set of five differently designed plates for the prints. Next, she was ready to use her dry-inking press to produce the prints. She inked one of the printing plates, which took one minute, and then ran it through her dry-printing press. The press printed a reverse image on a piece of paper.
She needed to re-ink the plate between each print. Sarah printed 41 paper prints from each inked plate. It required five minutes to run the dry-ink press to create one print from an inked plate. A batch consisted of the entire series of prints made from the set of plates. How many completed batches could Sarah produce in five nine-hour days?
