Answer:
$437,000
Explanation:
We first, find the net cash flow for the current period, and then, add the cash balance for the period immediately before.
Net cash flow for current period:
Cash provided by operating activities $310,000
Cash used by investing activities ($120,000) - we substract this because the cash was "used", that is to say, it was spent.
Cash provided by financing activities $149,000
Net cash flow: $339,000
Ending cash balance = Net cash flow + beginning cash balance
                  = $339,000 + 98,000
                  = $437,000
