Answer 1

To solve this problem, we need to set up a proportion with the given ratio and the number of blue cars.

Let x represent the number of red cars.

Then we can set up the proportion:

11/6 = 317/x

To solve for x, we use cross-multiplication:

11x = 6 * 317

11x = 1902

x = 1902/11

x ≈ 173

Therefore, there are approximately 173 red cars in the parking lot.
