Question

selena babysits on the weekends. the equation y= 12x represents the amount of money she earns . what is the constant rate of proportionality?

Answer 1

12

Explanation:

We have been given that Selena babysits on the weekends. The equation
`y=12x` represents the amount of money she earns. We are asked to find the constant of proportionality.

We know that two proportional quantities are in form
`y=kx`, where, y is proportional to x and k is the constant of proportionality.

Upon looking at our given equation, we can see that
`k=12`, therefore, the constant rate of proportionality is 12 for our given equation.

Answer 2

I believe below are the choices, it can be found elsewhere.

A. 1 B. 6 C. 12 D. 24

The constant rat of the proportionality of Selena is letter C which is 12.
To get the answer, the equation should be y = 12x
we can fill in the table for x and y. (we know that to obtain the y, we have to multiply the x, times 2. So if x was for example 1, then y is 12.) The y in this case represents the earnings, per each week x.
