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.

The answer is A.

Step-by-step 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.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
