. Ok, I just need to find the rate at which how many units one Kau eats per day.

So does everyone have the asnwer, i dont. Is C 12?

Okay, in this post I tell you what formula I used and what each variable stands for:

In this post I explain, step by step, how to use the formula to get the answer:

Try to follow along on a sheet of paper with my step-by-step explanation. The first thing you'll have to do is substitute the B and D values into the formula. Do you understand how to do this the way I explained it in my other post?

Yes, C is 12. So now that you have B, C, and D, you can substitute them into the equation and solve for A.

really... his makes no sense!!!! these LC aaaare no fun... but i think i am WRONG!!! meh

Hey, Werty, do you mind me asking how old you are?

Yes, C equals 12.
The whole equation is
3240/(48-12)=90.
Which is there for 3240/36=90.

Now what? I suck at math. Seriously.

Oh, and Kate, after this, can you tell me how many units does one Kau eat, and how many units the Grass replenish?

Themm, so now you've figured out what A and C are. Neopets wants to know how many Kaus it will take to clear the field in 16 days. So 16 is your D value. Now that you've got the A, C, and D values, all you have to do is plug them in and solve for B. So it would look like this:

3240 / (b - 12) = 16

Wow, thanks! You sure helped me A LOT!

To get the formula, I assumed that each Kau ate one unit of grass a day. The C value is the number of Kaus it would take to cancel out the growth of the grass, therefore keeping it at the same length. The B value is the number of Kaus we actually have, and the A value is the amount of grass on the field. So therefore, if you subtract the number of Kaus it takes to cancel out the growth of the grass from the amount of Kaus we have, then divide the amount of grass we have by that number, you'll get the number of days it would take for the Kaus to eat all the grass.

Hope that wasn't too confusing.

You're welcome. Glad I could help!

There is a really easy way to solve this. First, find out how many units of grass there was in total.
48 x 90 = 4320 units
30 x 120 = 3600 units
Now that you know that 4320 units of grass appear in 90 days, and that 3600 units of grass appear in 30 days, subtract the two units and you get how many units of grass are produced in 60 days. The answer is 720 units in 60 days. Then, divide 720/60 to find how much the grass grows a day. The answer is 12 units a day. Knowing that, find out how many units the grass grew in 90 days.
90 x 12 = 1080 units grown.
Therefore, since you know that 1080 of 4320 units were gorwn, subtract the two to find the starting amount of grass. The answer in 3240. And now since you are looking for 16 days, you have to find out how many units of grass will have grown in 16 days.
16 x 12 = 192 units.
Then, add that to the amount of grass that you started off with to find the total amount the cows must eat.
192 + 3240 = 3432 units
Now that you know how many units of grass the cows must eat, divide it by the number of days, and that will be how many cows there has to be.
3432/16 = This is your answer. (make sure you round up)

Well, this one is very simple math. I am born in june. I am in 5th grade and have never flunked. My age is 5 multiplied by how many ones are in the age i will turn in june. P.S. In June, I will be 11! lol

Note: This is NOT a simple proportion problem. I don't think 5th grade math covers this. If you thought it was really simple (and is in 6th grade or less) you probably got it wrong.

we know that!!! Are you trying to say thank 5th graders are NINCOMPOOPS!! Hehe.. Nincompoops... oh well, I just guessed. It IS hard... hmmm... My siggy might be changed to 'Embrace your wierdness' LOL

Time check.. srry.. got to know time diff.

it was just 4 hour diff.. NOW IT IS & HOuR???? hmm.... ohh... whoops. Iplayed w/ time thing.

WHOO!! FINALLY GOT MY TIME!!!!!!!

we know that!!! Are you trying to say thank 5th graders are NINCOMPOOPS!!

haha, not at all. I'm only saying that 5th graders have not learned enough to solve this problem on their own. (unless they are really smart)
