Question 3: Show the following verbal expressions (a,b,c,d) for two different sets with the appropriate mathematical symbols and definitions for two different sets of definitions.(predicate logic)
It is assumed that the first set of definitions is students in the class and the second set of definitions is all people. How could we express e option using propositional logic?

a) Some of the students in the class can speak German.
b) Everyone in the class is friendly.
c) There are those who are not born in California in the classroom.
d) A student from the class went to the theater.
e) Nobody in the classroom knows object-oriented programming.

I am having a difficult time with this loop. Needs to be in C++.

Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Ex: numRows = 2 and numColumns = 3 prints:

1A 1B 1C 2A 2B 2C 

#include <iostream>
using namespace std;

int main() {
int numRows;
int numColumns;
int currentRow;
int currentColumn;
char currentColumnLetter;

cin >> numRows;
cin >> numColumns;

cout << endl;

return 0;

You’ve been assigned to set the price at the local movie theater. You know that market demand can be broken into two groups, students and non-students. Those functions are: Students: p = 12 − 1/4q Non-Students: p = 22 − q (if you aggregated those functions, you would obtain p = 22 − q if p > 12 and p = 14 −1/5q if p ≤ 12). You’ve also been given the total cost and marginal cost for the theater. TC = 6 + 2q + q^2, MC = 2 + 2q

a) Plot the inverse demand curves for students and non-students. Make sure to also include both marginal revenue curves and supply curves, as well as labeling correctly.

b) Now, let’s assume that you can only charge one price for tickets. What is the equilibrium price, quantity and profits if you choose to act as a monopolist?

c) You’ve decided to try price discrimination for each group. What is the equilibrium price and quantity for students and non-students? What is your new total profit? Round answers to two decimal places.

d) Do the prices in part (c) make sense? Why would the price for one group be higher than the price for the other group?

e) What kind of price discrimination is this? Is there any way you can prevent arbitrage in this case? If so, how? Why is it important to prevent arbitrage in price discrimination?

EJH Cinemas, a movie theater next to your university, attracts two types of customers: those who are associated with the university (students, faculty, and staff) and locals who live in the surrounding area. There are 10,000 university customers interested in purchasing movie tickets from EJH Cinemas, with a maximum willingness to pay of $7 per ticket. There are 20,000 local customers interested in purchasing tickets, with a maximum willingness to pay of $9 per ticket. The movie theater incurs a constant marginal cost of $4 per ticket. For simplicity, assume each customer purchases, at most, one ticket.

a. What will be the amount of EJH Cinemas’ total revenue if the price is $7 per ticket?

b. What is the amount of consumer surplus if the price is $7 per ticket?

c. What will be the amount of EJH Cinemas’ total revenue if the price is $9 per ticket?

d. What is the amount of consumer surplus if the price is $9 per ticket?

e. If EJH Cinemas decides to practice price discrimination, charging $9 for a standard ticket available to everyone but only $7 for a ticket if you show your university identification (students, faculty, and staff), what will be the movie theater’s total revenue?

f. If EJH Cinemas decides to practice price discrimination, charging $9 for a standard ticket available to everyone but only $7 for a ticket if you show your university identification (students, faculty, and staff), what will be the amount of consumer surplus?

g. If you were in charge of EJH Cinemas, what pricing scheme should you use?

30. A popular resort hotel has 300 rooms and is usually fully booked. About 7% of the time a reservation is canceled before the 6:00 p.m. deadline with no penalty. What is the probability that at least 285 rooms will be occupied? Use the binomial distribution to find the exact value.

We are currently in the midst of a global pandemic. Are there any goods or services that may switch from “normal” to “inferior” or vice versa during this health crisis? Do you think any such changes will be permanent?
