Answer :

Final answer:

Troy should use the ratio of red-colored cars to total cars sold last year to estimate the number of red-colored cars to be sold next year by setting up a proportion and solving for the unknown.

Therefore correct option is 1

Explanation:

To predict the number of red-colored cars the dealership will sell if total sales are 885 in the next year, Troy should use the ratio of red-colored cars to total cars sold last year to estimate the number of red-colored cars to be sold next year. This method involves setting up a proportion where the number of red-colored cars sold last year is to the total sales last year as the number of red-colored cars predicted to be sold is to the total sales predicted for next year.

The ratio from last year is 270 red cars out of 625 total cars. If we expect 885 cars to be sold next year, the calculation would be (270/625) = x/885, where x is the number of red cars we're trying to predict. Solving for x gives us the estimated number of red-colored cars that will be sold.
