The percent change for Start: 45 End: 20 is 56 % decrease
The percent change for Start: 30 End: 60 is 100 % increase
Solution:
We have to find the percent increase or decrease between the starting and ending quantities below
The formula for percent change is given as:
[tex]\text { Percent change }=\frac{\text { End value - Start value}}{\text { Start value}} \times 100[/tex]
If the result is positive, it is an increase
If the result is negative, it is a decrease
1) Start: 45 End: 20
Substituting the values in above formula,
[tex]\text{ Percent change } = \frac{20-45}{45} \times 100\\\\\text{ Percent change } = \frac{-25}{45} \times 100\\\\\text{ Percent change } = -0.56 \times 100 = -56[/tex]
Thus the result is negative
So it is 56 % decrease
2) Start: 30 End: 60
Substituting the values in above formula,
[tex]\text{Percent change } = \frac{60-30}{30} \times 100\\\\\text{Percent change } = \frac{30}{30} \times 100\\\\\text{Percent change } = 100[/tex]
Here the result is positive
So it is 100 % increase
Answer:
-55.5% Decrease
100% Increase
Explanation:
20-45=-25
-25/45=-0.555
-0.555*100=-55.5%
60-30=30
30/30=1
1*100=100%
Hope this helps :)
