A) 18
B) 1
C) 15
D) 0

Answer 1

To approximate the number of red-colored cars in the parking lot, you can set up a proportion using the information given. The approximate number of red-colored cars in the parking lot is 18. Hence the correct answer is option A

Step-by-step explanation:

To approximate the number of red-colored cars in the parking lot, you can set up a proportion using the information given. If Mary found 2 red-colored trucks out of 15 trucks she looked at, we can assume that the proportion of red-colored trucks in the entire parking lot is the same.

Let x represent the number of red-colored cars in the parking lot. We can set up the proportion: 2/15 = x/140 and solve for x. Cross multiplying, we get 15x = 2 * 140, which simplifies to 15x = 280. Dividing both sides by 15, we find that x = 280/15 = 18.67.

Since we cannot have a fraction of a car, the approximate number of red-colored cars in the parking lot is 18. Therefore, the answer is Option A) 18.
