At the beginning of 2018, Wilson Stores has an inventory of $300,000. Because sales growth was strong during 2018, the owner wants to increase inventory on hand to $450,000 at December 31, 2018. If net sales for 2018 are expected to be $2,600,000, and the gross profit rate is expected to be 35%, compute the cost of the merchandise the owner should expect to purchase during 2018.
