Problem: South Coast Down Co. started 2020 with $94,000 of merchandise inventory on hand. During 2023, $400,000 in merchandise was purchased on account with credit terms of 1/15, n/45. All discounts were taken. Purchases were all made F.o.b. shipping point. South Coast paid fright charges of $7,500. Merchandise with an invoice amount of $5,000 was returned for credit. Cost of goods sold for the year was $380,000. South Coast uses a perpetual inventory system. If South Coast uses the gross method to record purchases, what's the cost of goods available for sale?
