Firms are able to price discriminate a. when all customers are uninformed about quality differences. b. when there is full information about quality available to all customers. c. when some customers are uninformed about quality differences. d. when no customers are uninformed about quality differences.

Option C

When some customers are uninformed about quality differences

Explanation:

Taking advantage that whereas some customers are uninformed about quality differences of the products sold by a particular firm, the management of the firm can easily discriminate prices for such customers,

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
