A shipping container will be used to transport several 120-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 12400 kilograms have already been loaded into the container. Which inequality can be used to determine xx, the greatest number of 120-kilogram crates that can be loaded onto the shipping container?

1 answer

The total weight of the crates already loaded is 12400 kilograms. The weight of each 120-kilogram crate can be represented as 120x, where x is the number of crates. So, the inequality would be:

120x + 12400 ≤ 27500.
