A COMPOSITE FUNCTION IS A COMBINATION OF TWO FUNCTIONS SUCH THAT THE OUTPUT FROM THE FIRST FUNCTION BECOMES THE INPUT FOR THE SECOND FUNCTION.
IN A COMPOSITE FUNCTION f[g(x)], SOMETIMES WRITTEN (fog) (x), THE OUTPUT OF FUNCTION G IS THE INPUT TO FUNCTION F.
Using proportions, it is found that:
- Each of Brendan and Clair get R 1387.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the total amount divided is R 4625.
For every R4 Andrew gets, both Brendan and Clair gets R3, hence the ratio is 4:3:3, which means that:
- Andrew gets
of the total amount.
- Brendan gets
of the total amount.
- Clair gets
of the total amount.
Then:


Hence:
- Each of Brendan and Clair get R 1387.5.
