Mark earns $1,250 for selling a $25,000 car. Which sale listed has the same commission rate?
A) $750 commission on a $15,000 car sale
B) $3,000 commission on a $30,000 car sale
C) $1,000 commission on a $40,000 car sale
D) $2,560 commission on a $32,000 car sale
I already know the answer is not D.

Answer 1

The answer is A.

Explanation:

If Mark earns 1250 for selling a 25000 car, that means he earns 5% commision because 1250 divided by 25000 is 0.05. And 0.05 equals 5%. Then you just try each of the answers. Since 15000 times 0.05 does equal 750, that means answer A has the same proportion as the example in the question.
