18 Sold merchandise on account $12,700, terms 3/10, n/30. The cost of the merchandise sold was $8,040. 20 Paid salaries $1,760. 23 Paid Gong Co. in full, less discount. 27 Received collections in full, less discounts, from customers billed on December 18. How do I answer 27? I do get how I do the math from 18. I know I credit cash and debit sales discount and accounts receivable but I don't know how to get the numbers. Please help!!
