Question

What is 108% of 4000?

Answer 1

`4320`

Explanation:

Calculate it exactly as it is written....

`108% of 4000 = 108/100 xx4000/1`

`= 4320`

An answer of more than 4000 is exactly what we expected because 100% of 4000 is 4000, but we are finding 108% which is more that 4000.

Answer 2

`108%` is another way to write `1.08`. So, if you take `108%` of `4000`, you multiply `4000` by `1.08`.

`color(blue)(108%xx4000)`

`= 1.08xx4000`

`= (1 + 0.08)xx4000`

`= (1 xx 4000) + (0.08 xx 4000)`

`= 4000 + (8/color(red)(cancel(color(black)(100))) xx 40color(red)(cancel(color(black)(00))))`

`= 4000 + (8 xx 40)`

`= 4000 + 320 = color(blue)(4320)`
