models salinity of ocean water to depths of 1000 meters at a certain latitude. x is the depth in meters and f(x) is in grams of salt per kilogram of seawater. Approximate the salinity (to the
Nearest hundredth) when the depth is 77 meters.
A) 31.67 g/kg
B) 56.83 g/kg
C) -27.13 g/kg
D) 54.43 g/kg

Question

Quizplus · Accepted Answer

Salinity cannot be negative, and it typically ranges between 30 to 40 g/kg for most ocean waters. The value 31.67 g/kg is within this expected range and is the most plausible estimate for salinity at a depth of 77 meters.
