You record the following data from the annual park cleanup day. based on the data, is there a direct variation or an inverse variation? explain your reasoning. volunteers- 5,10,20 hours- 12,6,3 show your work

Observe that as the number of volunteers increases, the number of hours required to complete the work decreases.  This is inverse variation.

Note that if we go from 5 volunteers to 10, the number of hours required drops from 12 to 6  Similarly, if we go from 10 volunteers to 20, the number of hours drops from 6 to 3.
