Im having a few troubles.

I do not know how to tell if something is a supppy or demand schedule.

I also cannot do the math.

If I could get help with that, would be great

The table below presents schedules A and B. One of them is a supply schedule and the other is a demand schedule for Swiss Francs (SF). Please answer the next three questions based on this information: Price of Schedules A Schedules B SF (Quantity of SF) (Quantity of SF so.85 1.000,000 0.84 2.000,000 50.83 3,000.000 082 4,000,000 S0.81 6,000,000 S0.80 8,000,000 10,000,000 8 ,000,000 6,000,000 4,000.000 2.000,000 1,000,000 17) What would happen if both the US and the Swiss governments fixed the price of SF at $0.81? The demand for SF would exceed the supply for SF and there would be a shortage of SF in the foreign exchange market. B. The demand for SF would be less than the supply of SF and there would be a shortage of SF in the foreign exchange market C. The demand for SF would exceed the supply of SF and there would be a surplus of SF in the foreign exchange market. D. The demand for SF would be less than the supply of SF and there would be a surplus of SF in the foreign exchange market. 18 What would happen if both the US and the Swiss governments fixed the price of SF at $0.842 A. There would be excess supply for 6,000,000 SF B.There would be excess demand for 200,000 SF C. There would be excess supply for 4,000,000 SF D. There would be excess supply for 2,000,000 SF 19, What should be the equilibrium price of SF in this market? A. $0.82 B. $0.83 C. $0.84 D. $0.85 20. Assume that British corporations want to purchase less from the US as a result of a weak British economy. This action reflects: A. an increased demand for British pounds B a decrease in the demand for British pounds C an increase in the supply of British pounds for sale D a decrease in the supply of British pounds for sale
