Aida bought a costume box containing 50 costumes for $300. she sold all of the costumes and made $250 profit. She sold all of the costumes for the same price. Use the equation 50c - 300 = 250 where c is the selling price of each costume what was the selling price of one costume in dollars?

it’s supposed to be -4+45=41

step-by-step explanation:

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

move it to the other side
