Question

test prep 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 represents this situation? show hints \\( 4m - 7 > 9 \\) \\( 4m - 7 < 9 \\) \\( 4m - 7 \geq 9 \\) \\( 4m - 7 \leq 9 \\)

Explanation:

Step1: Define Dwight's models

Let \( m \) be Walt's models. Dwight builds \( 4m - 7 \) models (7 fewer than 4 times Walt's).

Step2: Interpret "at most 9"

"At most 9" means Dwight's models \( \leq 9 \). So \( 4m - 7 \leq 9 \).

Answer:

\( 4m - 7 \leq 9 \) (the option with this inequality)
