For the situation below determine the independent value, the dependent value, and the constant of proportionality for both ratios. confirm your calculations by setting up a proportion with the two ratios and then cross-multiplying.

a package of 7 steaks costs $44.10. a package of 11 steaks costs $69.30.

see the explanation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Let

x ----> the number of steaks in the package

y ----> the cost

In this problem

The independent value or input value is the number of steaks (variable x)

The dependent value or output value is the cost (variable y)

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

First ratio

x=7, y=44.10 ---->  

Second ratio

x=11, y=69.30 ---->  

Verify the proportions

cross-multiplying

 ---> is true

therefore

The relationship between the variables, x, and y, represent a proportional variation
