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.

As a general rule, is it safe to assume that a change in the price of a good will always have its most significant impact on the quantity demanded of that good, rather than on the quantity demanded of miller goods? Explain.
answer please the last 2 sub questions The estimated demand for Canadian Processed Pork is given byQD = 171 − 20p + 20pB + 3pC + 2Ywhere QD is the quantity of pork demanded (millions of kg), p is the dollarprice per kg, pB is the price of beef per kg, pC is the price of chicken perkg, and Y is average consumer income in thousands of dollars. The supplyfor this market is given byQS = 178 + 40p − 60pB(a) According to the equations, what is the effect of an increase of pCon the market for pork? Specifically, which curve will shift, in whatdirection does the curve shift, and how will the equilibrium priceand quantity change (increase/decrease). On a corresponding graphof the supply and demand, draw the shifting curve and change inequilibrium. Note that no specific numbers are required here. Justthe direction of change.(b) Use the equations to solve for the equilibrium price of pork and quantity of pork as functions of the exogenous variables pB, pC , and Y .These will be linear…
The market demand for productXis given by: \[ Q_{d}=6-1 / 2 P \text { or } P d=12-2 Q \] The market supply for goodXis given by: \[ Q_{s}=-14+2 P \text { or } P s=7+1 / 2 Q \] whereP=price per unit andQis number of units.

What effect will each of the following have on the supply of auto tires? Microeconomics chapter 3 Supply is a schedule or curve showing the amounts of a productthat producers are willing to offer in the market at each possibleprice during a specific period. The law of supply states that otherthings equal, producers will offer more of a product at a high pricethan at a low price. Thus, the relationship between price and quantity supplied is positive or direct, and supply is graphed as anupsloping curve.The market supply curve is the horizontal summation of thesupply curves of the individual producers of the product.Changes in one or more of the determinants of supply (resource prices, production techniques, taxes or subsidies, the pricesof other goods, producer expectations, or the number of sellers inthe market) shift the supply curve of a product. A shift to the rightis an increase in supply; a shift to the left is a decrease in supply. Incontrast, a change in the price of the…
