Answer (2)
Answer:Let’s solve the given supply and demand equations step by step.Given Equations:Demand Equation: ( Q_d = 150 - p )Supply Equation: ( Q_s = -60 + 2p )To Find:Equilibrium Price and Quantity: Where ( Q_d = Q_s )Values for the given prices and quantities.1. Finding Equilibrium Price and QuantitySet ( Q_d ) equal to ( Q_s ):[ 150 - p = -60 + 2p ]Solve for ( p ):[ 150 + 60 = 2p + p ] [ 210 = 3p ] [ p = 70 ]Now, substitute ( p = 70 ) back into either equation to find the equilibrium quantity:[ Q_d = 150 - 70 = 80 ] [ Q_s = -60 + 2(70) = 80 ]So, the equilibrium price is 70 and the equilibrium quantity is 80.2. Filling in the TableFor ( p = 40 ):[ Q_d = 150 - 40 = 110 ] [ Q_s = -60 + 2(40) = 20 ]For ( p = 55 ):[ Q_d = 150 - 55 = 95 ] [ Q_s = -60 + 2(55) = 50 ]For ( Q_d = 80 ):Set ( Q_d = 80 ): [ 80 = 150 - p ] [ p = 150 - 80 ] [ p = 70 ]Substitute ( p = 70 ) into ( Q_s ): [ Q_s = -60 + 2(70) = 80 ]For ( Q_d = 65 ):Set ( Q_d = 65 ): [ 65 = 150 - p ] [ p = 150 - 65 ] [ p = 85 ]Substitute ( p = 85 ) into ( Q_s ): [ Q_s = -60 + 2(85) = 110 ]For ( p = 100 ):[ Q_d = 150 - 100 = 50 ] [ Q_s = -60 + 2(100) = 140 ]Completed Table:TablePresyo (p) Q_d Q_s40 110 2055 95 5070 80 8085 65 110100 50 140If you meant something else, please let me know!
The transition from nomadic to settled lifestyles in early human history was primarily influenced by the development of agriculture. This change allowed humans to cultivate crops, which led to the establishment of permanent settlements as people no longer needed to move in search of food.
