The percent of change from 100 to 27 is a 73% decrease. The percent of change is the value of a variable to which it gains or losses its magnitude.
The percent of change is calculated as follows:
% change = 100 × [final value - initial value]/(initial value)
The initial value is 100 and the final value is 27
So, the percent of change is
% change = 100 ×
= 100 × (-0.73)
= -73%
The negativesign indicates a decrease from the initial value to the final value.
Therefore, the percent of change from 100 to 27 is a 73%decrease. So, option A is correct.

The solution for 4x - 4 < 8 is x < 3
The solution for 9x + 5 > 23 is x > 2
The given inequality is:
4x - 4 < 8
Add 4 to both sides
4x - 4 + 4 < 8 + 4
4x < 12
Divide both sides by 4
The second inequality is:
9x + 5 > 23
Subtract 5 from both sides of the inequality
9x + 5 - 5 > 23 - 5
9x > 18
Divide both sides by 9
The solution for 4x - 4 < 8 is x < 3
The solution for 9x + 5 > 23 is x > 2
