Final answer:
Mirrlees Furniture paid out $225,000 in dividends from its $750,000 earnings since it has a 30% payout ratio. The remaining $525,000 was added to its retained earnings.
Step-by-step explanation:
Mirrlees Furniture earned $750,000 last year and had a 30% payout ratio. This means that the firm paid out 30% of its earnings as dividends. To calculate the amount added to retained earnings, we first need to determine the dividend paid and then subtract that from the total earnings.
The calculation for the dividends paid is as follows: $750,000 ×30% = $225,000. Consequently, the amount added to retained earnings is the earnings minus the dividends: $750,000 - $225,000 = $525,000. Therefore, Mirrlees Furniture added $525,000 to its retained earnings.
