2) Parker Company purchased merchandise from Liu Company with an invoice price of $30,000 and credit terms of 2/10,n/30. Liu Company's cost for the merchandise was $20,000. Vincent Company paid within the discount period. Assume that both buyer and seller use a perpetual inventory system and the gross method of recording invoices. 1. Prepare entries that Vincent should record for (a) the purchase and (b) the cash payment. 2. Prepare entries that Liu should record for (a) the sale and (b) the cash collection. 3. Assume that the buyer borrowed enough cash to pay the balance on the last day of the discount period at an annual interest rate of 8% and paid it back on the last day of the credit period.
