business calc demand functions

[krystaaanicole2890]

The demand functions for q_A and q_B
units of two related products, A and B, are given. Assume p_A and p_B
are in dollars.

qA	=	3000 − 80pA − 800 pB + 1
qB	=	11,000 − 700 pA + 8 + 700 pB + 8

(a) Find the marginal demand of q_A with respect to p_A.

∂qA

∂pA

= −80

(b) Find the marginal demand of q_A with respect to p_B.

∂qA

∂pB

=

(c) Find the marginal demand of q_B with respect to p_B.

∂qB

∂pB

=

(d) Find the marginal demand of q_B with respect to p_A.
