Which compound inequality is represented by the graph?

–3 ≤ x < 1
–3 < x ≤ 1
x ≤ –3 or x > 1
x < –3 or x ≥ 1

We are given a graph of compound inequality.

Given options are :

–3 ≤ x < 1

–3 < x ≤ 1

x ≤ –3 or x > 1

x < –3 or x ≥ 1.

In the graph, we can see that we have a solid dot on -3 and a hollow dot on 1.

Please note: A solid dot represents ≤ or ≥ inequality sign, because the number also included on which we have a solid dot.

And a hollow dot represents only < or > inequality sign.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
