Answer:
The percent (relative) change is 7.14 percent (%).
Step-by-step explanation:
We are given that the original support value is at 42%.
Then the support increased by 3%, to reach 45%.
We want the Percentage Change (i.e. relative) change of this increase, which can be computed as:
[tex]\frac{X_{F}-X_{O}}{X_{O}}*100[/tex]
where [tex]X_{F}[/tex] is the final value reached
[tex]X_{O}[/tex] is the original value
So plugging in our known values and computing we have:
[tex]\frac{45-42}{42}*100= \frac{3}{42}*100 = 0.071428*100=7.14[/tex] percent increase.
Now lets go back and check if we are correct.
[tex]42+42\frac{7.14}{100}=42+2.9988=42+3=45[/tex]
So it works!
