first question :

Market demand is given as Q = 140 - 4P Market supply is given as QS = 2P - 10 Suppose the government implements a tax of $9 on consumers. What is the value of consumer surplus after the tax? O a) $200 Ob) $126 O c) $98 O d) $196Market demand is given as QU = 140 - 4P Market supply is given as Q = 2P - 10 Suppose the government implements a tax of $9 on consumers. What is the change in consumer surplus as a result of the tax? a) $204 ( b) $252 O c) $102 O d) $196Market demand is given as Q = 140 - 4P Market supply is given as Q = 2P - 10 Suppose the government implements a tax of $9 on consumers. What is the value of total surplus after the tax? ( a) $600 Ob) $546 O c) $294 O d) $400Market demand is given as Q = 140 - 4P Market supply is given as Q - 2P - 10 Suppose the government implements a tax of $9 on consumers. What is the value of producer surplus after the tax? ( a) $196 ( b) $252 O c) $400 O d) $204Market demand is given as Q = 140 - 5P. Market supply is given as Q = 2P. In a perfectly competitive equilibrium, what will be the value of producer surplus? a) $160 ( b) $400 c) $800 ( d) $1100Market demand and market supply are given by Qd = 630 - 2P and Qs = 2P - 10. Suppose the government imposes a tax on the market and the after-tax supply is Qstax = 2P - 16. What price do consumers pay after-tax? *DO NOT include units, like the $ sign. *DO NOT leave any spaces before, in between or after your number. Round your answer to two decimal places
