Question

Can someone help with a simple question for a medal?

Answer 1

Tania has 56 liters of milk. She uses the milk to make muffins and cakes. Each batch of muffin requires 7 liters of milk, and each batch of cakes require 4 liters of milk. Let x be the number of batches of muffins and y be the number of batches of cakes that Tania can make.

Answer 2

How would I be able to translate that into an equation

Answer 3

1) name variables
2) assign variables

so multiply your x and y variables by the numbers given equal to...(let me see)

Answer 4

so you're making two separate equations

Answer 5

56 = ...

56 = ...

Answer 6

get it?

Answer 7

Yeah

Answer 8

Sooo what would the equation be?

Answer 9

I mean, I know how to get the answer once I have the equations, but word problems are my weakness.

Answer 10

type what you think it is and I'll tell you if you're right

Answer 11

Thats the thing, I don't know. If I did I wouldn't be asking for help

Answer 12

I'm not going to just give it to you.

Answer 13

Give me something, and we can go from there.

Answer 14

Give you what?

Answer 15

Oooohhhh, my bad lol hang on

Answer 16

Tania want to know the maximum amounts of either muffins or cakes:


With 56 liters of milk (and unlimited amounts of all other ingredients) how many muffins can she make? That is the first equation.

With 56 liters of milk (and unlimited amounts of all other ingredients) how many cakes can she make? That is the second equation.


(Remember that both equations are unrelated to each other; meaning, you start over with 56 liters of milk for the second equation.)

Answer 17

56x+7=4

Answer 18

?

Answer 19

I got you started before!
56 = ...
(equation one)

56 = ...
(equation two)

Answer 20

one equation uses x
the other uses y

Answer 21

56=7x+4 ?

Answer 22

two equations
one equation uses x the other uses y

Answer 23

I know its 2 equations, I just want to focus on one and when that one equation is right I will move onto the other

Answer 24

What a coincidence

Answer 25

First, you're mixing your muffins and cakes. They're separate.
56 = ?x
56 = ?y

Answer 26

So, 56=7x

Answer 27

And 56=4y ?

Answer 28

simplify (find x & y)

Answer 29

X=8
y=14

Answer 30

That it?

Answer 31

ya, correct

Answer 32

now you can visualize this problem by "combining" equations into a graph:

look for intersection of those numbers on the x & y axis...

Answer 33

Okay, thats all I need. Thanks
