4. Your firm produces a computer software called "Model It", which is sold to other businesses. Its demand has been estimated to be: QM = 550 - 4PM +1.5Ps - 2.SI, where, QM denotes units sold of "Model It" software, PM denotes "Model It's" price, Ps denotes the price of a best-selling competitor, and I is the average income of its consumers. a. Currently, PM = $110, Ps= $152, and I = 60. What is the estimated quantity demanded (QM) for "Model It" software? b. What is the change in QM that results from a one unit ($1) change in the PM? c. Holding the values Ps= $152 and I = 60 egnal state the demand function for "Model It"

Question
4. Your firm produces a computer software called "Model It", which is sold to other
businesses. Its demand has been estimated to be: QM = 550- 4PM +1.5PS - 2.SI, where, QM
denotes units sold of "Model It" software, PM denotes "Model It's" price, Ps denotes the price
of a best-selling competitor, and I is the average income of its consumers.
a. Currently, PM = $110, Ps= $152, and I = 60. What is the estimated quantity
demanded (QM) for "Model It" software?
b. What is the change in QM that results from a one unit ($1) change in the PM?
C.
Holding the values Ps= $152 and I = 60 equal, state the demand function for "Model It"
in the format QM = ao + a₁PM and its demand curve (inverse demand function) PM = a - bQM.
d.
Assume that the price of the competitor's product (Ps) changes from $152 to $172
and that I is still $60, state the new demand function for "Model It" (the format should be QM
= αo + α1PM) and its (inverse) demand curve (PM= a - bQM).
