Solve the inequality algebraically. write the solution in interval notation. |7x - 1| is greater than or equal to 4

The given inequality is

First we need to remove the inequality, and on doing so we will get two inequalities, which are

Adding 1 to both equations

Dividing both sides by 7

So the required solution is

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
