Answer:

q = 5000/x + 6

Step-by-step explanation:

D´= dq/dx = - 5000/x²

dq = -( 5000/x²)*dx

Integrating on both sides of the equation we get:

q = -5000*∫ 1/x²) *dx

q = 5000/x + K in this equation x is the price per unit and q demanded quantity and K integration constant

If when 1006 units are demanded when the rice is 5 then

x = 5 and q = 1006

1006 = 5000/5 +K

1006 - 1000 = K

K = 6

Then the demand function is:

q = 5000/x + 6
