Step-by-step explanation:
Let x represent the number of 40-kilogram crates to be loaded into the shipping container.
The total weight of these crates can be expressed as 40x kilograms.
The inequality representing the weight limit of the container is:
40x + 12100 ≤ 23500
Now, solve for x:
40x ≤ 23500 − 12100
40x≤11400
x ≤ 11400
40
x ≤ 285
Therefore, the solution to the inequality is
x ≤ 285
it is indicating that a maximum of 285 crates, each weighing 40 kilograms, can be loaded into the shipping container without exceeding the weight limit.
