Having trouble figuring this out. Please help with explanation. Thank you!!
1. Welfare effects of free trade in an exporting country Consider the Colombian market for soybeans. The following graph shows the domestic demand and domestic supply curves for soybeans in Colombia. Suppose Colombia's government currently does not allow international trade in soybeans. Use the black point (plus symbol) to indicate the equilibrium price of a ton of soybeans and the equilibrium quantity of soybeans in Colombia in the absence of international trade. Then, use the green triangle (triangle symbol) to shade the area representing consumer surplus in equilibrium. Finally, use the purple triangle (diamond symbol) to shade the area representing producer surplus in equilibrium.

Suppose that the Colombian government changes its international trade policy to allow free trade in soybeans. The horizontal black line (w) represents the world price of soybeans at $350 per ton. Assume that Colombia's entry into the world market for soybeans has no effect on the world price and there are no transportation or transaction costs associated with international trade in soybeans. Also assume that domestic suppliers will satisfy domestic demand as much as possible before any exporting or importing takes place. Use the green triangle (triangle symbol) to shade consumer surplus, and then use the purple triangle (diamond symbol) to shade producer surplus. 290 Domestic Demand Domestic Supply 306 350 Consumer Surplus PRICE (Dollars per ton) 236 320 Producer Surplus 306 290 276 260 246 230 0 26 60 76 100 125 150 175 200 226 250 QUANTITY (Tons of soybeans) When Colombia allows free trade of soybeans, the price of a ton of soybeans in Colombia will be $350. At this price, tons of soybeans will be demanded in Colombia, and tons will be supplied by domestic suppliers. Therefore, Colombia will export tons of soybeans.230 0 26 50 75 100 125 150 175 200 226 260 QUANTITY (Tons of soybeans) When Colombia allows free trade of soybeans, the price of a ton of soybeans in Colombia will be $350.

Using the information from the previous tasks, complete the following table to analyze the welfare effect of allowing free trade.
