Question

Ethan went to the store and purchased a new DVD player and some movies fro $532. Th cost of the movies was 3 times as much as the cost of the DVD player. find the cost of the DVD player and then the cost of the movies. let x represent the DVD player.

Answer 1

The equation is provided below:

x = cost of DVD player
3x = cost of the movies
$532 = total amount purchased for the DVD player and the movies

$532 = x + 3x
$532 = 4x
$532 / 4 = 4x / 4
$133 = x (cost of the DVD player)

$133 * 3 = $399 (cost of the movies)

To check if the equation is correct:

$532 = $133 + ( 3 * $133)
$532 = $133 + $399
$532 = $532

The correct answer for the cost of the movies will be $399.
