Question #13f34

Answer 1

`$72`

There are several ways to think about and answer this question.

One is to find the cost of coral in `$/(kg)` and then multiply by 8,000.
Or find the cost of coral in `$/(1000 kg)` and then multiply by 8.

Alternatively, we can think of this as a Proportion:

find the number `n` for which:

`n` is to `8000` as `27` is to `3000`

`n:8000 = 27:3000`

`n/8000 = 27/3000`

`3000*n = 8000*27`

`n=(8000*27)/3000 = (8*27)/3=8*9=72`
