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
