Final answer:
Without additional context or figures, such as closing stock or total expenses, it is impossible to calculate the missing carriage outwards figure from the provided balances. Collin should use the accounting equation and further details from his financial records to deduce the missing amount.
Step-by-step explanation:
To determine the value of the missing balance for carriage outwards, Collin needs to prepare a trial balance which involves totaling up all the debits and credits in the ledger accounts to see if they balance. However, the information provided does not directly reveal the missing carriage outwards figure. Instead, Collin should use the accounting equation (Assets = Liabilities + Equity) and his income statement to deduce the missing figure. Unfortunately, the data provided in the question does not give enough context or numbers to calculate the missing balance directly, as the necessary figures (such as opening stock, closing stock, or total expenses) to compute Collin's net income or loss – which could then be used to indirectly calculate the carriage outwards – are not mentioned.
