Final answer:

Matt needs to make his scale model of the Dodge Charger approximately 5 inches wide to stay proportional to the actual car that is 210 inches long and 117 inches wide, with his model being 9 inches in length.

Step-by-step explanation:

Matt wants to make a scale model of Dominic Toretto’s Dodge Charger from the movie Fast & Furious. The actual car measurements are 210 inches in length and 117 inches in width. Matt intends his scale model to be 9 inches long. To keep the model proportional, we need to find its width.

The formula to calculate the width of the scale model is:

Scale Width = (Scale Length / Actual Length) × Actual Width

Plugging the values we have into the formula:

Scale Width = (9 inches / 210 inches) × 117 inches = 0.0428571428571429 × 117 inches = 5.01 inches

Therefore, the width of Matt's scale model needs to be approximately 5 inches to stay proportional.
