during a recent fire, a 35-acre section (15 acres in North section and 20 acres in South section) of California National Forest was destroyed. The California Forest Department is planning to reseed both North and South sections with a density of a minimum 125 trees/acre and a maximum of 225 trees/acre. The department policy requires at least 40% of the trees in the north section and at least 60% of the trees in the south section to be white pine and the remainder to be yellow pine. White pine trees cost 3$ each, while yellow ones cost 2$ each. The cost of planting the white pine is 90$ per 100 trees, the cost of planting the yellow pine is 70$ per 100 trees. The department has been allocated 16,000$ for this project of which up to 11,000$ is allowed to be used in the purchase trees. (tree purchased must be planted). Formulate this a Linear Programming model that will aid california forest department to reseed the destroyed area.
