Normandy Office Products $($NOP$)$ makes two types of office desks, Manager and Executive. The Executive model is adjustable using

electic motors and is made with upgraded materials. The manufacturing process for the Executive model is more complex than that

for the Manager model, requiring more frequent inspections and shorter production runs. The Manager model is a basic desk, using

good, but easy to work with, materials, and is simpler to manufacture. NOP's results for the last fiscal year are shown in the following
