The demand and supply functions of beans are respectively given as 20QB +15PB- 5PR=6000 and 10QB-15PB=1200. Similarly, the demand and supply of rice are QR+PR- PB=250 and 3QR-7PR=710. PB and PR are prices of beans and rice. QB is demand of beans and QR is demand of rice. Find the equilibrium price and quantity of beans and rice. A rice and beans substitute? Explain you answer.

Determine the equilibrium price and quantity for the following laws of demand and supply in the manufacture of computer parts Demand: 3p + 5x = 200Bid:          7p - 3x = 56

Draw a demand and supply graph for each of the following questions. For each question, start by drawing a correctly labeled graph of the market for cookies in equilibrium. Your starting graphs should each have correctly labeled axes and demand and supply curves. Label the equilibrium price and quantity as p1 and p2 on the axes of each of the starting graphs. 1. Show the effect on the equilibrium price and quantity in the market for cookies if the price of milk increases. Determine which curve is affected by the change in the price of milk and whether it increases or decreases. On your graph, draw a new curve indicating the shift- either to the right or the left. Label the new equilibrium price and quantity as p2 and q2. 2. Show the effect on the equilibrium price and quantity in the market for cookies if the price of flour decreases. Determine which curve is affected by the change in the price of flour and whether it increases or decreases. On your graph, draw a new curve indicating…

At a price of $4.69 per pound, the supply for cherries is 16,210 pounds, and the demand is 10,280 pounds. When the price drops to $4.22 per pound, the supply decreases to 10,940 pounds and the demand increases to 12,746 pounds. Assume that the price-supply and price-demand equations are linear. What is the equilibrium quantity? Round to the nearest pound. pounds.
