An Interior Decorator Must Furnish Two Offices

Essay

An interior decorator must furnish two offices. Each office must have a desk, a chair, a file cabinet, and two bookcases. At a local office furniture store there are 6 models of desks, 8 models of chairs, 4 models of file cabinets, and 10 models of bookcases, all of which are compatible. (Any desk can be matched with any chair, etc.) How many choices does the decorator have if he wants to select 2 desks, 2 chairs, 2 file cabinets, and 4 bookcases but he doesn't want to select more than one of any model?
