A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

lord [1]

Answer:

Number of books = 4480.

Step-by-step explanation:

Given that fixed cost = $45920

Given that variable cost = $11.25 per book

Let number of books = x

then cost equation is given by 11.25x + 45920

Given that selling price of 1 book = $21.50

then selling price is given by 21.50x

Now we need to find about how many books must the publisher produce and sell so that the production costs will equal the money from sales.

So let's set both equal

21.50x = 11.25x + 45920

21.50x - 11.25x = 45920

10.25x = 45920

x = 45920/10.25

x = 4480

Hence number of books = 4480.

I need help with 1-8 I have no idea how to do this so it you would break to down that I can understand that would be great

For these fractions, you need to find a number that can divide the numerator and denominator by the same number. It needs to be simplified down till it can't be simplified any more.

1. 1/9

2. 12/18

3. 5/6

4. 36/45

5. 5/8

6. 6/8

7. 10/12

8. 20/36
