Pulling it together Scenario A local business would like for you to build a function to help calculate commission for their sales team. They have a 10 person sales force. No one had more than three sales during the pay period. If they are a junior (“jr” in the data) sales associate they get 5% commission on sales. If they are a senior (“sr” in the data) sales associate they get 10% commission on sales. Design the solution.

IPO Input Processing Output sale1 sale2 sale3 Associate level Sr Commission Rt (.1) Jr Commission Rt (.05) Processing Items Total sales Commission Rate Algorithm: Repeat 10 times Initialize Total sales = 0 Initialize Commission Rate = 0 Initialize Sale1, 2 and 3 = 0 Enter sale1 through sale 3 Enter Associate Level If associate level = “jr” set commission rate = jr commission rt Else set commission rate = sr commission rt End if Set total sales = sale1 + sale 2 + sale 3 Set commission amount = total sales * commission rate Output commission amount End Repeat Commission amount
