The Price-Demand equation regarding sales of a certain product is modelled as
Q=8000-20p+0.05p2
a)
Differentiate with respect to the variable t on both sides of the equation (using implicit differentiation)
B).to obtain a differential equation relating the rates of change of Q and p with respect to t.
If the price, p, is decreasing at a rate of $0.50/week, at what rate is the Demand changing when the current price is $20 ?
C).If the demand, Q, is increasing at a rate of 240/week, at what rate is the price changing when the current price is $40 ?

A demand function for Lenovo model SL computer is
Q=200-20P+0.04A+0.5Y
Where P = price of Lenovo, A = total advertising expenditure
for Lenovo and Y = disposable income of the consumers. Assume that
A = RM10,000 and Y=RM40,000.
a) Derive demand equation for Lenovo. Calculate the current
quantity demanded for Lenovo if its price is RM650.

Currently, the demand equation for necklaces is Q = 30 – 4P. The
current price is $10 per necklace. Is this the best price to charge
in order to maximize revenues? If not, what is?
Solve for the best price to charge in order to maximize
revenues. Show any steps or processes used to reach the answer
above. Explain your process as though you are teaching the concept
to a student who is a beginner in economics.

The demand price for a certain brand of CDs is modeled by the
function D(q) = −0.01q2 − 0.2q + 12, where p is the wholesale unit
price in dollars and q is the quantity demanded each week, measured
in thousands of discs. The supply price for the CDs is given by the
function S(q) = 0.01q2 + 0.6q − 3, where price is the wholesale
unit price in dollars and q stands for the number of CDs that will...

Given the demand equation and MC in problem # 1 (demand
equation: Q = 40 – 0.5P. Marginal cost is MC = $20.), suppose the
firm decides to offer quantity discount by selling the product in
bundles of 10 units. Answer the following questions. A graph would
help you with this question, but you do not need to include the
graph in your answer.
