Question 1070114:  A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will total $50,560. The variable costs will be $8.50 per book. The publisher will sell the finished product to bookstores at a price of $24.50 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?

You can  put this solution on YOUR website! First, write the equation for the production of the books: 
p = 8.50b + 50,560 
This equation shows that for the production, $8.50 is paid per book and $50,560 have to paid anyway. 
Now, write the equation for the sales: 
s = 24.50b 
Now, set both of the equations equal to each other because the sales and production money have to be equal, as asked in the question. 
p = s 
8.50b + 50,560 = 24.50b 
50,560 = 16b 
3,160 = b 
3,160 books must be produced and sold.

You can  put this solution on YOUR website! x = number of books.
 
 
cost = 50,560 + 8.50 * x
 
 
revenue = 24.5 * x
 
 
break even is when revenue equals cost.
 
 
revenue equals cost equation becomes:
 
 
24.5 * x = 50,560 + 8.50 * x
 
 
subtract 8.50 * x from both sides of the equation to get:
 
 
24.5 * x - 8.5 * x = 50,560
 
 
combine like terms to get:
 
 
16 * x = = 50,560
 
 
divide both sides of the equation by 16 to get:
 
 
x = 50,560 / 16 = 3160.
 
 
replace x in the original cost and revenue equations to get:
 
 
cost = 50,560 + 8.50 * x becomes cost = 50,560 + 8.50 * 3160 which gets you cost = 77,420.
 
 
revenue = 24.5 * x becomes revenue = 24.5 * 3160 which gets you revenue = 77,420.
 
 
solution looks good.
 
 
he will have to sell 3160 books to break even.
