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.
