Answer:
Black is 3.57%
Green is 96.43%
Step-by-step explanation:
Since 27 green than black
Let the black car be b
So green cars which 27 more than black means 27b
So to calculate the percentage of green we will have
27b/27b+b ×100
27b/28b ×100
Let's eliminate the b
27/28×100
2700/28
96.43%
So let's calculate for Black
b/27b+b ×100
b/28b ×100
Eliminate b
1/28 ×100
100/28
3.57%
Therefore the percentage for Black is 3.57% and for green is 96.43%

Step-by-step explanation:
y=8x+6
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.
