The table shows, for five companies A-E, the number of employees who prefer their own vehicle and the percentage who prefer Metro and Bus. These are the only three modes, so the own-vehicle share is the percentage left after Metro and Bus.
| Company | Own vehicle (number) | Metro | Bus |
|---|---|---|---|
| A | 184 | 68% | 24% |
| B | 78 | 60% | 35% |
| C | 384 | 55% | 30% |
| D | 182 | 70% | 16% |
| E | 220 | 72.5% | 15% |
What is the difference between the number of employees who prefer Metro from companies D and E together and the number who prefer Bus from companies A, D and E?
