The table below shows the linear relationship between the number of delivery trucks, , in a fleet and the total weight, , of their cargo (in kilograms). Which equation represents the linear relationship between and ?
| Number of trucks | Total cargo weight (kg) |
|---|---|
| 2 | 110 |
| 4 | 210 |
| 7 | 360 |
50t - w = -10
50t - w = 10
50w - t = -10
50t + w = 10
