Detailed Answer
Answer (D) is correct. The firm has daily sales of $45,000 consisting of 150 units at $300 each. For 30 days, sales total $1,350,000. Of these sales, 40%, or $540,000 ($1,350,000 × 40%), will be uncollected because customers do not take their discounts. The remaining $810,000 ($1,350,000 × 60%) will be paid within the discount period.
