there are 27 more green cars than black cars in the parking lot. What percentage of the cars in the parking lot are green? What percent are black?

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%
