(a)
Write an expression for the company’s total revenue in terms of
The expression revenue in terms of x is given by
Given:
The price p is given as
Calculation:
It has been given that
Therefore, the revenue is given by
Hence, the expression revenue in terms of x is given by
(b)
Write a function for the company’s profit P to make x radios.
The profit function given by
Given:
The price p is given as
The cost of making one radio is $15.
Calculation:
It has been given that
Cost of making one radio is $15.
Hence, the cost of making x radios is given by
Therefore, the profit function is given by
(c)
Write and solve an equation to find a lesser number of radios that the company could produce and still make the same profit.
The company could produce
Given:
The profit function given by
The company produces 1.5 million of radios and generate a profit of $24,000,000.
Calculation:
It has been given that
For the profit to be $24,000,000.
In order to find the values for x, graph the equations
The positive x-value other than
So, the company could produce
(d)
Do all the solutions in part c makes sense. Explain.
All these solutions don’t make sense. Only the positive values of x will give the number of radios to generate a profit of $24,000,000.
Given:
The profit function given by
The company produces 1.5 million of radios and generate a profit of $24,000,000.
Calculation:
It has been given that
For the profit to be $24,000,000.
In order to find the values for x, graph the equations
From the graph, there are three solutions
Hence, the solution
Therefore, all these solutions don’t make sense. Only the positive values of x will give the number of radios to generate a profit of $24,000,000.
