Answer the following based on the following inverse demand or price function for item X

P = 100 - Q

the Total revenue function is

A) TR = 100Q - 100Q2 B) TR = Q - 100Q2 C) TR = 100 - 100Q2 D) TR = 100Q - Q2

19) based on theinverse demandP = 100 - Q, the Marginal Revenue function is

A) MR = 100 - 2QB) MR = 100 - 2Q2C) MR = 100Q- 2QD) MR = 100Q- 2Q2

20) based on theinverse demandP = 100 - Q, TR is at a maximum when Q is ___ units and P is ____

A) 50 ; $50B) 100 ; $100C) 50; $100D) 100 ; $50

21) based on theinverse demandP = 100 - Q, the point price elasticity of demand when MR = 0 is

A) -1B) -2C) 0D) -0.5
