The greatest load that fits in the container is 24500kg
There are already 11300Kg loaded
Let x indicate the number of 40Kg crates, then 40x symbolized the total weight of the crates loaded.
You can express the inequality as
[tex]11300+40x\leq24500[/tex]From this expression we can calculate the number of crates that can be loaded as follows:
[tex]\begin{gathered} 11300+40x\leq24500 \\ 40x\leq24500-11300 \\ 40x\leq=13200 \\ \frac{40x}{40}\leq\frac{13200}{40} \\ x\leq330 \end{gathered}[/tex]You can load up to 330 crates into the container.
