It costs a publishing company $50000 to make books. The $50000 is a fixed cost or a cost that cannot change. To help the publishing company sell the books, a marketing company charges $4 for each book sold. If the company sells the book for $9 each, how many books should they sell to breakeven?

Graph your results.

To calculate the breakeven point, we need to find the number of books the publishing company needs to sell in order to cover its fixed cost.

Let's denote the number of books they need to sell as "x".

The revenue obtained from selling x books is given by the equation:
Revenue = Selling Price * Number of Books
Revenue = 9 * x

The cost incurred by the publishing company is the sum of the fixed cost and the variable cost per book sold:
Cost = Fixed Cost + (Variable Cost per Book * Number of Books)
Cost = 50000 + (4 * x)

For the breakeven point, the revenue should equal the cost:
9 * x = 50000 + 4 * x

Simplifying the equation:
9x - 4x = 50000
5x = 50000
x = 10000

Therefore, the publishing company needs to sell 10,000 books to break even.

To graph the results, we can create a simple line graph. The x-axis would represent the number of books sold, while the y-axis would represent the total cost and revenue.

On the x-axis, mark the values from 0 to 20,000, increasing by increments of 2,000 (or as appropriate for your graph).

On the y-axis, mark the values from 0 to 120,000, increasing by increments of 20,000 (or as appropriate for your graph).

Plot the breakeven point at (10,000, 50,000) on the graph.

Now, draw the revenue line by connecting the point (0,0) to the breakeven point (10,000, 50,000). The line should have a positive slope.

Next, draw the cost line by connecting the point (0, 50,000) to the breakeven point (10,000, 50,000). The line should have a flat slope.

The two lines should intersect at the breakeven point.

To calculate the breakeven point for the publishing company, we need to consider both the fixed cost and the variable cost per book.

In this case, the fixed cost is $50,000, which means it remains constant regardless of the number of books sold. The variable cost is the marketing company's charge of $4 per book sold.

Let's denote the number of books to be sold as 'x'.

The revenue from selling 'x' books can be calculated as the selling price per book multiplied by the number of books sold:
Revenue = Selling Price * Number of Books Sold = $9 * x

The total cost can be calculated as the sum of the fixed cost and the variable cost per book multiplied by the number of books sold:
Total Cost = Fixed Cost + (Variable Cost per Book * Number of Books Sold) = $50,000 + ($4 * x)

For the breakeven point, the revenue should equal the total cost:
Revenue = Total Cost

Now we can set up the equation:
$9 * x = $50,000 + ($4 * x)

Simplifying the equation:
$9 * x - $4 * x = $50,000
$5 * x = $50,000

Dividing both sides of the equation by $5 to solve for 'x', we find:
x = $50,000 / $5
x = 10,000

Therefore, the publishing company needs to sell 10,000 books to break even.

To graph the results, you can create a simple line graph with 'Number of Books Sold' on the x-axis and 'Revenue' and 'Total Cost' on the y-axis. Plot the points where the revenue and total cost are equal for different values of 'x' until you reach the breakeven point of 10,000 books sold.

The publisher evidently makes 9-4 = 5 dollars per book.

It evidently costs 50,000 to print any number of books (strange, typo maybe)
5 x = 50,000
x = 10,000
