A freight elevator has a weight limit of 2 tons. Each crate that is loaded weighs 80 pounds. What is the greatest number of crates that can be loaded onto the elevator? (1 ton = 2,000 pounds)

First, let's convert the weight limit of the elevator to pounds. A ton is equal to 2,000 pounds, so the weight limit is 2 tons * 2,000 pounds/ton = 4000 pounds.

The weight of each crate is 80 pounds.
To find the greatest number of crates that can be loaded onto the elevator, we divide the weight limit of the elevator by the weight of each crate: 4000 pounds / 80 pounds/crate = <<4000/80=50>>50 crates.
Therefore, the greatest number of crates that can be loaded onto the elevator is 50.

To calculate the maximum number of crates that can be loaded onto the elevator, we will first convert the weight limit of the elevator to pounds.

1 ton is equal to 2,000 pounds, so the weight limit of the elevator is 2 tons x 2,000 pounds/ton = 4,000 pounds.

Now, we need to determine how many crates weighing 80 pounds each can fit into 4,000 pounds.

4,000 pounds / 80 pounds/crate = 50 crates.

Therefore, the greatest number of crates that can be loaded onto the elevator is 50 crates.
