Question

Help please!

Answer 1

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
$30,952
. The variable costs will be
$9.50
per book. The publisher will sell the finished product to bookstores at a price of
$22.75
per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?

Answer 2

I have forreal been stuck all day....so sorry if i'm slow just really tired

Answer 3

Given that the variable costs are
$9,50 per book, write an expression for the total variable costs as a function of x (the number sold).

Answer 4

similarly, figure out a formula for the total revenue when x books are sold.

Answer 5

so i should write a expression

Answer 6

okay let me think of one

Answer 7

yes, an algebraic expression, one for each case.

Answer 8

Three things will show up in your expression: unit cost or unit sales price, number sold, total cost or total revenue.

Answer 9

P=30,952+9.50*B

Answer 10

What about that :/

Answer 11

OMG, nvm

Answer 12

good start, but this formula is for total production costs, not for the profit (P).

Answer 13

you won't believe what just happend

Answer 14

I'm using aleks math website and for some reason the page refreshed with a whole new problem -.- so ugh..

Answer 15

it sayssnow

Answer 16

Deon will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of
$57.96
and costs an additional
$0.07
per mile driven. The second plan has an initial fee of
$53.96
and costs an additional
$0.12
per mile driven. How many miles would Deon need to drive for the two plans to cost the same?

Answer 17

that happens occasionallyl. ;(

You need to equate (total production costs) to (total revenue from sales). then solve that for x.

Answer 18

try to get back to the previous question.

Answer 19

Aight let me see

Answer 20

Nope won't let me, apparently this is the new problem it wants me to solve

Answer 21

Try hitting the "previous page" arrow in the upper left hand corner of your screen. Do that a couple of times. If not successful, we'll switch to this new problem. Better save the URL of this new problem before you try to find the old one.

Answer 22

I hit the back button like you said a couple of times to bring me back to the old screen with the original problem. Than i hit refresh just to make sure i can stay on that page without any problems. But it ended just loading up the same new problem again. so i guess we have to sole that one

Answer 23

copy and paste this URL:

Answer 24

just did lol what did it change :o?

Answer 25

$57.96 + $0.7/mile * x = $53.96 + $0.12/mile * x

Answer 26

will that equation work

Answer 27

If nothing has changed, then open a new tab and paste that URL .

Answer 28

i just did sir

Answer 29

it brought me back to this page

Answer 30

scroll all the way up to the top of this page. You'll see the original problem, probably. if you do, copy the orig. problem and paste it at the bottom of this discussion.

Answer 31

Oh yah i see the original problem atop but there's no need in solving it because i'm supposed to solve the other problem now.

Answer 32

OK. Find the new problem, copy and paste it at the bottom of this conversation.

Answer 33

Deon will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of
$57.96
and costs an additional
$0.07
per mile driven. The second plan has an initial fee of
$53.96
and costs an additional
$0.12
per mile driven. How many miles would Deon need to drive for the two plans to cost the same?

Answer 34

Will this work for it
$57.96 + $0.7/mile * x = $53.96 + $0.12/mile * x

Answer 35

You need to write two linear equations, one for each different car rental firm.

You could let the total car rental cost for the first firm be TRCA(x)
and the total car rental cost for the second firm be TRCB(x).

Can you write both formulas using the price info give to you?

Answer 36

i can try...Not that good at it

Answer 37

hmm

Answer 38

can't think of it :(

Answer 39

TRCA(x) = fixed, up-front cost PLUS daily rate times x (x is the number of days).

Your turn.

Answer 40

TRCB (x) fixed up front cost 53.96
+
0.12M
miles driven

Answer 41

Yes, so TRCB(x) = $53.96 + 0.12m, where m represents the # of miles driven. Good.
TRCA(x) = ?

Answer 42

TRCA (x)= $57.96 + 0.7m

Answer 43

Btw sorry for wasting your time D:

Answer 44

that's 0.07, not 0.70. You're not wasting my time. ;)

Answer 45

Fix TRCA(x).

Answer 46

oh i missed that
so
TRCA (x)= $57.96 + 0.70m

Answer 47

No, TRCA(x)=57.96 + 0.07m.
Now set TRCA = to TRCB and solve the resulting equation for m.

Answer 48

my parents want me to go to bed.. sorry was trying to stay up to do this
But i think that answer is 80 something

Answer 49

It's actually $80. congrats!
I'll say good night now. See you again. Welcome to OpenStudy!!

Answer 50

Not $80, but 80 miles. Sorry.

Answer 51

bye for now!
