A table shows the densities of a juice at various concentrations:
| Concentration (%) | Density (kg/m^3) |
|---|---|
| 50 | 1200 |
| 60 | 1300 |
| 70 | 1400 |
Assuming the density varies linearly with concentration, what is the predicted density, in kilograms per cubic meter (), at 65% concentration?
1,325
1,350
1,375
1,400
