Question

I really need help with understanding this problem. Can someone plz go through this with me?

Answer 1

Emily uses her college photocopier machine to photocopy at the rate of $0.08 per page. She decides to rent a photocopier machine for $90 a year. The cost of photocopying using the rented machine is $0.03 per page.

Part A: Write an inequality that can be used to calculate the number of pages that Emily should photocopy in a year so that the amount she pays for the rented machine is less than the college machine. Define the variable used. (5 points)

Part B: How many pages should Emily print in a year to justify renting the photocopier? Show your work. (5 points)

Answer 3

I don't know how to solve it by myself but we can work together, OK?

Answer 4

Now, let x is the number of pages Emily print / year
then the cost she has to pay for college is 0.08*x right?

Answer 5

do you know what \(\color{red}{per}\) mean ???

Answer 6

yes

Answer 7

what represent per ??/

Answer 8

But if she uses rented machine, what is the cost for it? Calculate it now:
The machine rented cost: $90
x pages * 0.03 = $0.03 x
all cost is ------------------------------
90+ 0.03x
that is the cost she has to pay if she uses rented machine, ok?

Answer 16

90+0.03x < 0.08x

Answer 17

And that's the answer to Part A, right?

Answer 18

yup, now, let it look more beautiful by let the term has "x" in one side, number in another side. then you are done

Answer 19

yep per mean each
but i was saying that per mean slope and its mean you should have x with that number :):P
