If 3 eggs can make 9 muffins, how many eggs nedeed to make 12 muffins?

4 eggs

Step-by-step explanation:

*In algebra, this is what we would call a direct variation, ergo if x(eggs) goes up, y (amount of muffins) also goes up as well.

1.) Use the formula for direct variation

e= amount of eggs

m= amount of muffins

k= constant of variation

2.) Find the constant of variation, substitute numbers with the given info above.

3.) Solve for the direct variation, substitute the variables with the new set of info.

i'm confused with your question, first of all it seems that your statement is missing a little details, like how many dogs she's walking? but if that's not the case and your teacher tells you that you can put any number of dogs then here's the equation.

a-number of dogs

b-number of how much she earns

c-number of times she does this

a×b×c=n

ex.

3×5×2=30 -jane earns 30 dollars just by walking 3 dogs on the weekends.
