Answer:
Hello your question is poorly written attached below is the complete question
Answer :
a) R'( 120 ) = 3000
b) Increase the manufacturers revenue
Step-by-step explanation:
Given data:
F (120) = 9000 pairs
F' (120) = -50 pairs of shoes
R(p) = P * F(p)
a) find R' ( p )
R'(p) = P * F'(p) + F(p) * 1
∴ R' ( 120 ) = 120 * ( -50 ) + 9000 * 1
= 3000
b) A small Increase in price by $3000 will Increase the manufacturers revenue
