The demand schedule for the product 'xyz' is given below:
Price($) Quantity demanded
3 20
4 15
5 11
6 9
7 7
Task: Based on the above data, solve the questions given below:
Compute the pointpriceelasticity of demand for an increase in the p

Sir/ma'am,
I am having a hard time understanding how to solve the following two quantitative problems. I am supposed to be able to solve for this problem given any set of values. Please feel free to make those up. I am just hoping to understand how to solve this problem if and when it comes up.
See attachment.
Thanks

Inverse, Direct Demand Function, & PointPriceElasticity
Copy and paste the following data into Excel:
a) Run OLS to determine the inverse demand function (P = f(Q)); how much confidence do you have in this estimated equation? Use algebra to then find the direct demand function (Q = f(P)).
b) What is the pointprice elasti

A manufacturer has estimated that the demand for its product as
Qx = 500 - 2Px + .5I + .65Pz - 1.8Py
where Qx is the quantity demand, Px is the price, I is average annual income (currently $14,000). Pz and Py are the prices of related goods. Total costs are given by TC = 3,500,000 + 500Q
Suppose that PZ= $300

A company has the following demand function for its product.
Q=40,000-200P+500I+100Px
Where P is the price of the firm's product, I is household disposable income in thousands of $, and Px is the price of a competitor's product.
The firm charges a price of $ 100 per unit.
Estimated household income = $ 50. (in thousan

Demand for cassettes can be characterized by the following point elasticities:priceelasticity =-2,cross priceelasticity with aaa batteries is -1.5, and income elasticity =3. please explain the following statement.
a. A 3% price reduction in cassette players would be necessary to overcome the effects of a 2% decline in inco
