Arecipe for 2 dozen corn muffins calls for 3 cups of flour. the number of muffins varies directly with the amount of flour you use. write a direct variation equation to represent this.

A direct variation equation to represent this ;  

Step-by-step explanation:

Direct Variation states that a relationship between two variables in which one is a constant multiple of the other one.

In other words, when one of the variable changes then the other changes in proportion to the first.

If b is directly proportional to a, then the equation is in the i.e,

form where k is the constant of variation.

Let y represents the number of muffins and x represents the amount of flour.

It is given that the number of muffins varies directly with the amount of flour you use.

As per the given statement:

y = 2 dozen corn and x = 3 cups of flour.

Then, by definition of Direct variation;

y = kx

Substitute the given values to find k;

Divide both sides by 3 we get;

then, equation is,

Therefore, a direct variation equation to represent this situation is;
