Let's assume
a babysitting job where the amount you earn as 'A'
number of hours you work as 't'
now, we are given
You have a babysitting job where the amount you earn is directly proportional to the number of hours you work.
so, we get
![A=kt](https://img.qammunity.org/2019/formulas/mathematics/college/ydzgqgicw2ju5n3qbilfklte3qf2ddspe9.png)
where
k is constant of proportionality
now, we can solve for k
![k=(A)/(t)](https://img.qammunity.org/2019/formulas/mathematics/college/c1guu36kumiu0s5kylbw3nu14ibd6qlt5i.png)
so, the constant of variation represents in this situation is the amount you earn per hour............Answer
