Remark
This is much the same as the last inequality that you posted. When it tells you that you have 1 condition that is more than and one condition that is less than, then you need a compound statement. One of A and B is correct. C or D never will be.
At Least 4
This is the more than condition. You need 4 or more pennies to add to the collection. The rule is the same. The pointy end always points towards the smallest amount
4 ≤ x
No more than 2
That means that you can have 2 or under. The pointy end points to the x
2 ≥ x The biggest number (open end of the arrow) points at the 2.
Answer
2 ≥ x or 4 ≤ x That means the answer is A
