Mr. Bennett owns 4 restaurants. The mean number of tables is 30. Which number line shows what could happen to the mean if he buys two new restaurants, one with 15 tables and another with 9 tables?
Number of tables al four restaurants have; = 4 * 30 =120 tables Two new restaurants + 4 =6 restaurants (120+15+9)= 144 tables Mean = total # of tables/ total # of restaurants; 144/6 =24 This is the mean so it decreases. I hope this helps even though you didn’t actually post the number line
