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?
Correct answer: C. 75%
- A. 30%
- B. 50%
- C. 75%
- D. 125%
Explanation
The question asks us to determine how much greater the number of blue cars is compared to the number of red cars in percentage terms. First, calculate the number of blue and red cars: 7% of 500 is 35 blue cars, and 4% of 500 is 20 red cars.The difference between the number of blue and red cars is 35 - 20 = 15. To find how much greater the number of blue cars is than the number of red cars, use the formula: (difference / number of red cars) x 100% = (15 / 20) x 100% = 75%. Therefore, the number of blue cars is 75% greater than the number of red cars. Option C is correct because it reflects this calculation accurately, while the other options do not match the computed percentage difference.
