An extract from Marble & Sons cash flow forecast for September is shown below - OCR - GCSE Business - Question 8 - 2022 - Paper 1

To determine the opening balance, we can apply the cash flow formula:

$\text{Closing Balance} = \text{Opening Balance} + \text{Net Cash Flow}$

Rearranging this, we find:

$\text{Opening Balance} = \text{Closing Balance} - \text{Net Cash Flow}$

Substituting the provided values:

• Net Cash Flow = £-2600
• Closing Balance = £7300

Thus:

$\text{Opening Balance} = 7300 - (-2600)$

This simplifies to:

$\text{Opening Balance} = 7300 + 2600 = 9900$
