Alessia and her two sisters each paid 20% of the cost of a new dvd player. their parents paid for the remainder, which was $48. how much did the dvd player cost?

The cost of the DVD player was $120

Step-by-step explanation:

we know that

Alessia and her two sisters each paid 20% of the cost of a new DVD player

so

Alessia and her two sisters paid 60% of the cost of a new DVD player

Their parents paid for the remainder ($48) > 100%-60%=40%

therefore

40%> represent $48

applying proportion find the cost of the DVD player

$48/40%=x/100%

x=100*48/40

x=$120

answer: the answer is 110

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
