Who can answer a question of mine?
It has two parts
if there is 60 5 lemon juice what percentage of water is in the mixture?
* 60 %
right so if there is a total of x liters in the bottle we have 0.4x = 1 because theer is 1 liter of water
solve this for x
So what would the equation look like?
theres a total of 2.5 liters of the mixture in the bottle Part B volume of lemon juice = 0.6 * 2.5
the equation is 0.4x = 1
where x is the volume of lemon juice+ water
What does the * stand for again?
Oooh I see. So I need to multiply 0.6 and 2.5?
60% = 0.6
thats correct 1.5 liters of lemon juice are in the mixture
Awesome! Ya think you can help me with one more?
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)
Sorry No I have to go right now,
Oh alright. Thank you!
Answered that photocopy question years ago.
Good luck finding it
... You're not going to help me..?
Do you have an idea Of how to set it up?
Not one bit. Never really understood inequalities.
What We want: Cost of rented photocopier < Cost of college photocopier
The cost of both are given in the problem . All you have to do is write the appropriate expression for each
what is the cost of the rented photocopier?
That's what I need most help with
What does the last sentence of the first paragraph say?
.03 per page
Yes,µ+ we don't know how many pages gµ will have to photocopy in order for the price of photocopying using the rented machine to be less than that of the College machine.
So we should let ''per Page" represent x
So the cost of photocopying using the rented machine is represented by .03x
Actually yes 90 + .03x is correct
Which means the cost for photocopying using the college machine is...?
Where does 3000 come from?
I divided 90/.03
For what reason?
Wait, was I supposed to solve 90 + .03x?
What was the last thing I asked you to find?
The cost for photocopying with the rented copying machine
We found the expression for the cost of using the rented machine already.
What is the cost for using the other machine?
Oh oops 0.08
So knowing this, how should We setup the inequality?
I don't know; it only says the cost per page.
Remember we want cost of rented machine < Cost of college machine
Replace each with their appropriate expressions.
... Not sure
The cost per page adds UP to the total cost of using each machine.
If you have something like 200 pages worth Of stuff to photocopy, it's going to cost More than just $0.08
So for part A, we need to find an amount of pages that will be cheaper with the rented copier?
because i looked at his profile it says he's offline
