In an effort to replace the destruction of trees, five regions of the US have been tracking the annual rate of trees being planted (per thousand) in each region and the annual rate of trees being destroyed (per thousand). Additionally, the tree population (in thousands) by region has been recorded for five different years. The data is given in the tables below. Determine the number of trees planted and the number destroyed in each of the years listed.
Rate of Trees Being Planted | Rate of Trees Being Destroyed | |
Northeast | 0.0341 | 0.0115 |
Southeast | 0.0174 | 0.0073 |
Midwest | 0.0185 |
0.0056 |
Southwest | 0.0131 | 0.0082 |
West | 0.0096 | 0.0105 |
