True or false? the below is a maximization model:

The seasonal yield of Piraeus, Greece, vineyard is greatly influenced by the process of branch pruning. If olive trees are pruned every two weeks, output is increased. The pruning process, however, requires considerable more labor thanpermitting the olives to grow on their own and results in a smaller olive size. It also, though, permits olive trees to be spaced closer together. The yield of 1 barrel of olives by pruning requires 5 hours of labor and 1 acre of land. The production of olives by the normal process requires only 2 hours of labor, but takes 2 acres of land. An olive grower have 250hours of labor available and a total of 150 acres for growing. Because of the olive size difference, a barrel of olives produced on prune trees shows a profit of $20 whereas a barrel of regular olives shows a profit of $41. The grower has determined that because of uncertain demand, no more than 40 barrels or pruned olives should be produced.
