Joanne was making repairs to her deck and needed to buy some supplies. She purchased two posts, three boards, and four piers for $$52$. Needing more materials, she went back to the lumberyard and bought one post and five boards for $$13$. Realizing she did not need the piers she made a third trip where she bought three more boards, returned the four piers and ended up with a refund of $$34$. What was the cost of each item?
