A studio that makes statues is trying to minimize its expenses. Their two primary products are the Venus and Colossus statues. Each Venus requires 18 hours of machine time to rough cut the shape and 72 hours of artist time to finish the details. The Colossus requires 36 hours on the machines and 8 hours with the artist's hand. The studio has pre-paid for 324 hours of machine time and 144 hours of artist time, so they want to use at least that much each day. Both use 30 pounds of stone. The studio needs to use at least 300 pounds of stone per day to keep their warehouses from overflowing. If each Venus incurs expenses of eighty-nine dollars, and each Colossus is sixty-two dollars, we want to know how many statues of each type the studio should make each day.

Let V represent the number of Venus statues and C represent the number of Colossus statues. Identify the constraint(s) below.
