A milk processing factory currently has 9 tons of fresh milk. If the fresh milk is sold directly on the market, a profit of 500 yuan per ton can be made. If it is processed into yogurt, a profit of 1,200 yuan per ton can be made, and if it is processed into milk slices, a profit of 2,000 yuan per ton can be made. The factory's production capacity is as follows: if processed into yogurt, 3 tons can be processed per day; if processed into milk slices, 1 ton can be processed per day. Due to personnel restrictions, the two processing methods cannot be carried out simultaneously. Due to temperature restrictions, this batch of milk needs to be sold or processed within 4 days. For this reason, the factory has designed two plans:
Plan 1: Make as many milk slices as possible, and sell the remaining fresh milk directly;
Plan 2: Make some into milk slices, the rest into yogurt for sale, and just finish within 4 days.
Which plan do you think will make the most profit, and why?
