Answer 6

1% is 1 part out of a 100.
to get this 1, you can multiply 100 by 0.01, which results in 100.

In order to calculate for example 5% of 200, you multiply 200 by 0.05, which is 10.
To get 43.5% out of 83,023 you simply multiply 83,023 by 0.435, which is 36,115.

So in your case:
4000 * 0.065 =
1500 * 0.08 =
