A seller uses a perpetual inventory system, and on April 17, a customer returns $1,000 of merchandise previously purchased on credit on April 13. The seller's cost of the merchandise returned was $480. The merchandise is not defective and is restored to inventory. The seller has not yet received any cash from the customer. Complete the two journal entries (the first for the revenue part of the transaction and the second for the cost part) to record the sales return transaction by selecting the account names and dollar amounts from the drop-down menus

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
