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%
$26.50
2(3)=6
8.50 + 12.00+ 6= 26.50
