Question

the independent variable, x, represents the number of hours babysitting. the dependent variable is the amount of money earned, because the number of hours babysitting depends on the number of hours babysitting. a function relating these variables is a(x)=6x. so a(3)=18, meaning 3 hours of babysitting will get 3 hours of babysitting.

Explanation:

Step1: Identify the function

The function is given as $A(x)=6x$, where $x$ is the number of hours babysitting.

Step2: Substitute the value

We need to find $A(3)$. Substitute $x = 3$ into the function $A(x)$. So $A(3)=6\times3$.

Step3: Calculate the result

$6\times3 = 18$.

Answer:

18
