Rienzi Farms grows sugar cane and soybeans on its $500$ acres of land. An acre of soybeans brings a $$1000$ contribution to overhead and profit; an acre of sugar cane has a contribution of $$2000.$ Because of a government program no more than $300$ acres may be planted in soybeans. During the planting season $1200$ hours of planting time will be available. Each acre of soybeans requires $2$ hours, while each acre of sugar cane requires $5$ hours. The company seeks maximum contribution $($profit$)$ from its planting decision.
