. Sony Ent. is marketing a new smartphone. It determines that in order to sell x smartphones, the price per product must be It also determine that the total cost of producing x smartphones is given by

a. Find the total revenue, R(x).
b. Find the total profit, P(x).
c. How many smartphones must the company sell in order to maximize profit?
d. What is the maximum profit?
e. What price per smartphone must be charged in order to maximize profit?

To answer these questions, we need to have the equations for total revenue, total cost, and total profit in terms of the number of smartphones sold. Let's assume that the price per smartphone is represented by "p", and the total cost is represented by "C(x)".

a. To find the total revenue, R(x), we multiply the price per smartphone by the number of smartphones sold, x:
R(x) = p * x

b. To find the total profit, P(x), we subtract the total cost from the total revenue:
P(x) = R(x) - C(x)

c. To maximize profit, we want to find the value of x that gives the maximum P(x). This can be done by finding the derivative of the profit function P(x) with respect to x and setting it equal to zero. Then solve for x.

d. To find the maximum profit, we substitute the value of x obtained in step c into the profit function P(x).

e. To find the price per smartphone that maximizes profit, we substitute the value of x obtained in step c into the price function p(x).

However, the equations for the total cost and the price per smartphone are missing in your question. Please provide the equations for the total cost and the relationship between the price per smartphone and the number of smartphones sold so that we can continue to solve the problem.
