Out of a population of 1,000 students, 80 were asked by a random sampling what color they would prefer for their first car. Their responses are shown in the table below.Car ColorFavorite ColorNumber of StudentsBlue5Red18Gray27Silver14White16Using proportional reasoning, how many students out of the 1,000 would you expect to prefer a silver car?
In the sample, 14 out of 80 students preferred silver. Scale that proportion to 1,000 students: (14 ÷ 80) × 1,000 = 175. So you would expect 175 students to prefer a silver car.
