Juan is planning to paint a room. He spends $39 on brushes, $83 on paint, and $17 on a drop cloth. Use the Associative Property of Addition to write two equivalent expressions that show the total cost. How can using the Associative Property of Addition make it easier to find the total cost? What is the total cost?
