Final answer:
For June, the net cash flow is calculated by subtracting expenses from receipts, resulting in $225, and the cumulative balance is then updated by adding this net cash flow to the previous month's balance, resulting in $1,545.
Step-by-step explanation:
The student's question involves calculating the missing amounts for net cash flow and cumulative balance in a hypothetical monthly financial statement. For June, we need to calculate the net cash flow by subtracting the total expenses from the total receipts. The cumulative balance for June can then be determined by adding the net cash flow of June to the cumulative balance of May. To solve, we take the June receipts of $1,050 and subtract June expenses of $825, giving us a June net cash flow of $225. This net cash flow is then added to the May cumulative balance of $1,320 to arrive at a June cumulative balance of $1,545, rounded to the nearest whole number.
