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

12

Step-by-step explanation:

We have been given that Selena babysits on the weekends. The equation 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 , where, y is proportional to x and k is the constant of proportionality.

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

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
