- Clearance A department store is clearing out merchandise in order to make room for new inventory. The plan is to mark down items by 30% each week. This means that each week the cost of an item is 70% of the previous week’s cost. If the original cost of a sofa was $1,000, the cost for the first week would be $1000(0.70) and the cost of the item during the second week would be $1,000(0.70)2. Complete the table shown below.
