May you please assist with the following problem

Patricia has just graduated university and is thinking about opening "Surf Shop" to sell surfboards. Basic surfboards are manufactured by a local company and the cost to purchase each surfboard is $500. Patricia is quite artistically talented and plans to paint a scene on each surfboard so that each surfboard is unique. The estimated cost for paint and supplies is $50 per unit and the direct labor cost to do this is zero. Pat estimates that each unique surfboard can sell for $1,000.00. Other costs include rent for the shop of $34,000 annually and advertising of $26,000 annually. Patricia plans to hire one salesperson who will be paid a 15% sales commission for every surfboard that is sold. Required: You must show all your calculations in order to get marks.
