December 31 2014, cash = $486,000
Explanation:
To solve this, we will classify the particulars as either income or expenditure,and find the difference. This is shown below:
Particulars                          income($)                 expenditure($)
operating activities            531,000                     -
investing activities             -                                  963,000
financing activities             585,000                    -
January 1 cash balance     333,000                     -
Total                                   1,449,000                  963,000
∴ net cash available on December 31 2014 = Total income - expenditure
= 1,449,000 - 963,000 = $486,000
