The owner of a greenhouse and nursery is considering whether to spend $6,000 to acquire the licensing rights to grow a new variety of rosebush, which she could then sell for $6 each. Per-unit variable cost would be $3. If her available land has design and effective capacities of 3,000 and 2,000 rosebushes per year respectively, and she plans to grow 1,200 rosebushes each year on this land, what will be the utilization of this land?
