C. 42%

D. 4%

Answer: A. 40%

Step-by-step explanation:

to find the percentage decrease, first you have to subtract $6,300 from $10,500, which equals $4,200. This is the amount decreased from the price of the car. Then, to find the percentage that $4,200 is to $10,500, you have to divide 4,200 by 10,500. This should give you 0.4, the percentage is this number multiplied by 100. This should give you the number 40, which means that the percentage decrease of the price of the car; 40%.

Answer:40%

Step-by-step explanation:

Percentage decrease = (10500-6300) / 10500 * 100

Percentage decrease=4200/10500*100/1

Percentage decrease = (4200*100) : (10500*1)

Percentage decrease=420000:10500

Percentage decrease=40
