Question

Of the 500 cars displayed in a certain car dealer, 7 percent are blue and 4 percent are red. The number of blue cars in the car dealer are what percent greater than the number of red cars?

Answer 1

The number of blue cars is 75% greater than the number of red cars.

Step-by-step explanation:

To find the percentage by which the number of blue cars is greater than the number of red cars, we need to compare the two percentages. The number of blue cars is 7% of the total 500 cars, which is 0.07 * 500 = 35. The number of red cars is 4% of the total 500 cars, which is 0.04 * 500 = 20. Therefore, the number of blue cars is 35 - 20 = 15 greater than the number of red cars. To find the percent by which the number of blue cars is greater than the number of red cars, we can divide the difference (15) by the number of red cars (20) and multiply by 100: (15 / 20) * 100 = 75% greater.
