The demand for a certain brand of portable alarm function is given by:

p = - 0,01.x^2 - 0,3x + 10

Where p is the unit price at the wholesale real ex, the quantity demanded each month, measured in units of thousands. The bid for this watch brand function is given by:

p = - 0,01x^2 + 0,2x + 4

Having po same meaning as before and where x amount, in thousands, that the supplier will market monthly. Determine the consumer surplus and the surplus production when the unit market price is equal to the equilibrium price.

amistre64 · Answer

i believe equi price is when demand is equal to supply 


- 0,01.x^2 - 0,3x + 10  = - 0,01x^2 + 0,2x + 4 

 - 0,3x + 10  = 0,2x + 4 

10  = 0,5x + 4 

6  = 0,5x

12 = x

but i cant be sure that my definintion for equi price is valid

anonymous · Answer

understood because they speak the demand function is given by 
p = - 0,01.x^2 - 0,3x + 10 
and the supply function is given by: 
p = - 0,01x^2 + 0,2x + 4 
dai ele quer saber o excedente do consumo e o excedente de produção, quando o preço unitário de mercado é igual ao preço de equilíbrio, fiquei meio confuso em relação a esse exercício...
