Problem

The farmer in Problem 25 has an opportunity to take over the neighboring 80-acre farm. If he acquires this farm, he will be able to increase the amounts of time available to 1,600 hours for planting, 825 hours for tending, and 1,400 hours for harvesting. Between the two farms, there are 510 units of water and 6,000 pounds of fertilizer available. However, the neighboring farm has not been cultivated in a while. Therefore, each acre of this farm will take an additional 4 hours to plant and an additional 2 hours to tend. Because of the condition of the new farm, the farmer expects the yields per acre planted there to be only 46 bushels, 37 bushels, 42 bushels, and 45 bushels, respectively, for corn, tomato, potato, and okra. In order to make sure that both farms are used effectively, the farmer would like at least 80% of each farm's acreage to be planted. What is the best combination of crops to plant at each farm in order to maximize revenue?
