Answer 2

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

`\text { Percentage change }=\frac{\text {Final value-Initial value}}{\text {Initial value}} * 100`

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,

`\text { Percentage change }=(45-50)/(50) * 100 \%`

`=(-5)/(50) * 100 \%`

Negative sign indicates percentage decrease .Percentage change cannot be in negative, therefore we ignore the negative sign.

`=(5)/(50) * 100 \%`

`=(1)/(10) * 100 \%`

= 10%

Therefore the percentage change from 50 to 45 is 10%
