Problem
Barbara Duff manages a marina with her sister, Sheryl. To moor sailboats to the dock, the sisters needed rope. A maritime wholesaler was selling 5/8 inch twisted strand polypropylene rope in 500 foot rolls. The store had paid $123.64 per roll for the rope. For the sisters, the hardware store marked up the rope 20% above their cost. Compute the dollar markup and the selling price that the sisters would pay for one roll of the rope.
