The appropriate relation is ...
current weight + additional weight ≤ elevator capacity
Filling in the given values, we get ...
2375 pounds + additional weight ≤ 2800 pounds . . . . . your inequality
additional weight ≤ 425 pounds . . . . . subtract 2375 pounds (the solution)
The elevator can hold up to 425 additional pounds.
