Answer:
The percentage change if I decrease 50 to 45 is 10%
Solution:
We have to find the percentage change if I decrease 50 to 45.
To calculate the percentage change we use the below given formula
[tex]\text { Percentage change }=\frac{\text {Final value-Initial value}}{\text {Initial value}} \times 100[/tex]
Here 50 is decreased to 45.
Hence the initial value is 50 and the final value is 45.
Substituting the initial and final values in the formula we get,
[tex]\text { Percentage change }=\frac{45-50}{50} \times 100 \%[/tex]
[tex]=\frac{-5}{50} \times 100 \%[/tex]
Negative sign indicates percentage decrease .Percentage change cannot be in negative, therefore we ignore the negative sign.
[tex]=\frac{5}{50} \times 100 \%[/tex]
[tex]=\frac{1}{10} \times 100 \%[/tex]
= 10%
Therefore the percentage change from 50 to 45 is 10%
