A joint cost funclion is defined implicitly by the oquation c+c=10+qA16+qB2 wheere c denotas the fotal cost (in dollars) for producing qA units of product A aind qE units of product 8 : (a) If qe=4 and ce=3. find the corresponding value of c (b) Determirie the marginal costs with respect to Q4 and Pe whan quA=4 and qee=3. (a) If qk=4 and qB=3, the coeresponding value of c is 25 (5implify yout answer) (b) The marginal cost with respect to qA when q4=4 and qe=3 is (Simplity your answer)
