Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds. Dwight builds at most 9 models. Which inequality could be used to find the number of models Walt builds?

A) 4m - 7 < 9

B) 4m - 7 ≤ 9

C) 4m - 7 >9

D) 4m - 7 ≥ 9

   inequality could be used to find the number of models Walt builds. Correct option B).

Step-by-step explanation:

Here we have , Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most 9 models. We need to find Which inequality could be used to find the number of models Walt builds . Let's find out:

Let the  the number Walt builds is x , So Dwight builds 7 fewer models than 4 times the number Walt builds i.e.

⇒

But , according to question Dwight builds at most 9 models i.e.

⇒

⇒

⇒

⇒

Therefore ,    inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
