Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.

Answer:

y=4x

Step-by-step explanation:

Two variables have a proportional relationship if the ratio of one variable to the other is constant.

A proportional relationship between x and y can be modeled by the equation y=kx.

The letter k is the constant ratio of y to x. It is called the constant of proportionality.

The ratio for each pair of x- and y-values is 4. So, the variables have a proportional relationship.

So, the constant of proportionality is 4 ounces of almonds per ounce of dark chocolate.

The equation for the relationship is:

y=4x
