Last ballet season, the Avante-Garde Ballet company purchased items from all three companies as shown in the following table. The cost of these items are given in the following chart. Jones Beach Jones Beach has a jetty on its westernmost edge, a swimming area is on its easternmost edge, and a volleyball play area in between. One sunny day, you notice that one in six of the people in the volleyball area stroll to the jetty every hour, while two in six stroll over to the swim area. Due to the bad jellyfish infestation, half the beach goers at the swim area meander over to the volleyball area every hour, while the rest of them stay put.
Nobody leaves the jetty.
The above data can be summarized in the following table.
