Q. Suppose demand and supply for koby beef are described by following equations: QD = -150P + 500; QS= 100+100P, where P is price in dollars, QD is quantity demanded in thousands of pounds per year and QS is quantity supplied in thousands of pounds per year.
a. Find equilibrium price and equilibrium quantity by solving equations mathematically.
Suppose a Research study is published showing that koby beef increases risk for a heart attack resulting in a reduction of 150 pounds of koby beef consumption per year.
b. Determine new equilibrium price and quantity by solving equations mathematically.
