Hey there!!
The number is no more than 50.
This statement states that the number can not be more than 50.
This number is less than 50 and equal to 50 but not more than that.
Hence, the values of the number could be less than 50 or equal to 50.
But, the highest or the supreme number is 50.
Hence, the inequality would be:
... x ≤ 50
Hope my answer helps!
