Answer:
Explanation:
First, simplify the equation they give you
125x+200≥1200 ---------> 125x≥1000---------->x≥8
So, x has to be greater than or equal to 8 which rules out b or d.
So the answers are narrowed down to a and c, the only difference is that the dot in A is filled in whereas the dot in c is not. In math, having a filled in circle means that value is included (≥ sign), so we will choose the answer a.
