Answer:
$600
Step-by-step explanation:
Under the cash basis, the cash surplus is reported as profit which is calculated as under:
Cash Surplus = Cash inflow - Cash outflow
Here cash inflow are the receipt of cash which includes $400 and $300. Furthermore, the cash outflow includes $100 only.
So by putting values, we have:
Cash Surplus = ($400 + $300) - $100 = $600
This cash surplus of $600 will be reported as net income for the year under the cash basis of accounting.
