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 $53,533. The variable costs will be $12.50 per book. The publisher will sell the finished product to bookstores at a price of $24.25 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?
Answers
9514 1404 393
Answer:
4,556
Step-by-step explanation:
Revenue from the sale of n books is ...
R = 24.25n
Production cost for n books is ...
C = 53533 +12.50n
These are equal for ...
24.25n = 53533 +12.50n
11.75n = 53533
n = 53533/11.75 = 4556
The publisher must produce 4556 books so sales will equal production cost.

Complete Question
Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum=7, maximum = 83, 6 classes
What is the class width? (whole number)
We have that the Class Width is given as
7-19
20-32
33-45
46-58
59-71
72-84
Generally
[tex]Class\ width =\frac{83-7}{6}[/tex]
Class width =12.67
Class width =13
Hence
Lower class limit is
7,7+13=20...33,46,59,72
Upper class limit is
7+13-1=19,32,45,58,71,84

Answer:
The answer is t(2844 + 1491) or t(4335)
Step-by-step explanation:
18 x 150 = 2700
18 x 8 = 144
2700 + 144 = $2844
21 x 65 = 1365

126 + 1365 = 1491
t = ? <--- t stays the same

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c.
C=39.95+.15(s+r)
If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.
Answers
Answer:
The total number of text messages sent was 27.
Step-by-step explanation:
The monthly cost of the cell phone plan, in function of the number of text messages sent(s) and the number of messages received(r), is given by:
[tex]C = 39.95 + 0.15(s + r)[/tex]
In this question, we have that:
[tex]C = 53.45, r = 63[/tex]
We put this into the equation to find the value of s. So
[tex]C = 39.95 + 0.15(s + r)[/tex]
[tex]53.45 = 39.95 + 0.15(s + 63)[/tex]
[tex]0.15s + 9.45 = 13.50[/tex]
[tex]s = \frac{13.50 - 9.45}{0.15}[/tex]
[tex]s = 27[/tex]
The total number of text messages sent was 27.
