Question

i will medal and fan whoever answers this!!!


it costs $10 to make earphones
the start up cost for manufacturing are $5,000
how many earphones must be produced to get to a cost per unit of $20?

Answer 1

what subject is this for

Answer 2

algebra 1b

Answer 3

I am not sure

Answer 4

Do you have any answer choices for this?

Answer 5

no saddly

Answer 6

sorry don't know the answer

Answer 7

So, i can't guarantee that i know how to do this, but what i seem to be getting is the result that you need to produce 500 earphones, and that's because, we know that we want to get a result of 20, so we set the rest equal to that, the other side are the units, like this\[20=\frac{cost }{ units }\]so we are told that the cost is 10 per unit, and that the start up is 5000, that means\[cost = 5,000+10x\]and x is our variable her which is how many units we want to produce, so what you need to solve is\[20=\frac{ 5000+10x }{ x }\]which i found to be 500, again, i'm not entirely sure that's correct

Answer 8

wow thank you can you help with another?

Answer 9

I think you are right

Answer 10

simplify 4/5b^3 times 7/2b^2

Answer 11

I am not really sure but I am just saying what I think

Answer 12

a.14/5b^6
b.8+35b/10b^2
c.14/5b^2
d.28/10b^2

Answer 13

\[\frac{ 4 }{ 5b^3 }*\frac{ 7 }{ 2b^2 }\]so you just have to multiple across, nothing special\[\frac{ 4*7 }{ 5b^3*2b^2 }\]the only trick to remember, is that when you multiply something that has the same base number, but different powers, you need to ADD those powers together, so for instance\[a^5*a^6=a^{5+6}=a^{11}\]

Answer 14

are you sure those are the answers, the result should be\[\frac{ 28 }{ 10b^5 }=\frac{ 14 }{ 5b^5 }\]

Answer 15

but that is not a choice

Answer 16

yes i am sure

Answer 17

Does my work look like the problem that you were given?

Answer 18

yes

Answer 19

Then i have to stand firm and say that your answer choices are wrong, and i can't tell which one your teacher expected you to pick, probably a), but otherwise none of those answers are correct.

Answer 20

hmm ok thank you for helping
