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.

Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
