profit and cost is maximised when MR=MC

p=24-0.1q

TR=PQ

=(24-.1Q)q

TR=24Q-0.1q2q^2

MR=d(TR)dQ\frac{d(TR)}{dQ} =24-0.2q


TC=TC1+TC2

TC=0.1q12^2 +0.05q22^2

MC1=d(TC1)dQ1\frac{d(TC1)}{dQ1} =0.2q1

MC2=d(T2)d2\frac{d(T2)}{d2} =0.1q2


mr1=mc1

24-0.2q1=0.2q1

24=0.4q1

q1=60


mr2=mc2

24-0.2q2=0.1q2

24=0.3q2

q2=80

remember Q=q1+q2

Q=60+80

Q=140

P=24-0.1Q

P=24-(0.1×140)\times140)

p=$10


b) profit=TR-TC

TR=QP

=140×\times 10

=$1400


Tc1=0.1×\times602^2

=0.1×\times 3600

=$360


tc2=0.05×\times 802^2

=0.05×\times 6400

=$320

TC=360+320

=680

TC-TR

=1400-680

Profit=$720


c)

price=profit divide by quantity

720140\frac{720}{140} =$5.14
