Answer:
1. 15%
2. 85%
Step-by-step explanation:
The graph is 100 units,
the shaded part is 15 units,

17.46% of 126 is 22
Divide 22 by 126:

Change the decimal into a percentage by multiplying the decimal by 100:
Distribute the two: 2x + 6 = 18
Subtract the six: 2x = 12
Divide by two: x = 6
That's your answer!
