Question #22a7a

Answer 1

The new yearly salary will be $16800.

Explanation:

`16000 + 16000 * 5%`

We may now factor out our initial value of `16000`.

`16000 * (1 + 5%)`

And because `1 = 100%`:

`16000 * 105%`

`16000 * 1.05`

`16800`

In fact, this process is not specific to this case or situation. Whenever we have some percentage change and the initial value, we may calculate the final value.

Let `v` represent the initial value.
let `r` represent the change as a percentage.

Our final value can be expressed as follows:

`v + v*r/100`

Once again factoring out `v`,

`v * (1 + r/100)`

`v * (100 / 100 + r/100)`

`v * (100+r)/100`
