Which of the following word problems can be solved using the inequality 9x+18>72

Step-by-step explanation:

In this question, I see an outlier. Most of the time you may want to solve the inequality, but check how the answers are phrased in relation to the inequality. The equation shows a > symbol.

Answer A states, "save at least $72." If the inequality used a greater than or equal to sign this could work, yet it uses a > symbol. I would go with B & C, if you haven't chosen already.

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
