Step-by-step explanation:
To determine the cash expected to be collected in December as a result of current and past credit sales, we need to calculate the cash collections for each month and add them up.
In September, the cash collected would be 20% of $154,000, which is $30,800. In October, the cash collected would be 55% of $154,000 (collected in October) and 20% of $145,000 (collected in September), which is $84,700. In November, the cash collected would be 55% of $145,000 (collected in November), 20% of $129,000 (collected in October), and 20% of $154,000 (collected in September), which is $102,900. In December, the cash collected would be 55% of $129,000 (collected in December), 20% of $145,000 (collected in November), and 20% of $129,000 (collected in October), which is $104,150.
Therefore, the company can expect to collect $104,150 in cash in December as a result of current and past credit sales.
