Hello I am having trouble with an agriculture economics question, I cannot seem to understand the steps on calculating the change in consumer surplus and change in producer surplus in the exporting country after the trade started to happen? I have provided images of the three panel diagram and question below.

All questions are based on the following three panel diagram. A. The U.S. B. International C. The Rest of the World's Motorbike Market Motorbike Market Motorbike Market Price Price Price ($/unit) ($/unit) ($/unit) Soop /Sus pretrade 5000 World price price with trade. 2500 2500 Sex Exports St 2500 Import: Dus 1750 1750 DEX 10 40 70 Quantity 60 Quantity 15 45 75 Quantity (thousands) (thousands) (thousands) 5us = U.S. supply Sy = Rest-of-world supply of exports Sy = Rest of world's supply Dus = U.S demand (S, = 5, - DF) D/ = Rest of world's demand Don = U.S. demand for imports (D m = Dus - Sus)Calculate the change in consumer surplus and change in producer surplus in the exporting country after trade started to happen
