Answer:
11.67
Explanation:
Given: Employee earn $175 for 15 hours
We know, the constant of variation means the rate of change.
To know The constant of variation, we need to find how much employee earn each hour.
∴ Constant of variation=
![(Total\ earning)/(Total\ working\ hours)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jcysl8mbr8lav0s1pupfb5iwu06xx9yxng.png)
Constant of variation=
![(175)/(15)= 11.666](https://img.qammunity.org/2020/formulas/mathematics/middle-school/eqmtgv0wxqz182kldaqbb3xkblp9lgjbdw.png)
∴ Constant of variation= 11.67. (rounding off)
