Answer:
                            Hard       Soft        Plastic
San Francisco	3,600           7,800       12,000  
Los Angeles  2,400            1,800        3,000	
Explanation:
The sales during January were as follows:
                           Hard      Soft          Plastic
San Francisco	600              1,300           2,000  
Los Angeles  400                300              500
If the sales during the next five months were actually the same, then to determine total sales all we have to do is multiply January's sales by 6.
600 x 6 = 3,600         1,300 x 6 = 7,800         2,000 x 6 = 12,000
400 x 6 = 2,400           300 x 6 = 1,800            500 x 6 = 3,000
