Let's define variables:
x1: Friend 1 contribution for the business
x2: Friend 2 contribution for the business
x3: Friend 3 contribution for the business
The total contribution is:
![C = x1 + x2 + x3 C = 500 + 350 + 200 C = 1050](https://img.qammunity.org/2019/formulas/mathematics/middle-school/rfu7l9871f2kj181r66qs10m00pw2pcx6o.png)
The percentage that each one contributes is given by:
![Pi = = (xi / C) * 100](https://img.qammunity.org/2019/formulas/mathematics/middle-school/zaiebdxp33x298c3sbfxkz3mumu5kd152u.png)
Where,
i = 1, 2, 3
Calculating we have:
![P1 = (x1 / C) * 100 = (500/1050) * 100 = 47.61904762 P2 = (x2 / C) * 100 = (350/1050) * 100 = 33.33333333 P3 = (x3 / C) * 100 = (200/1050) * 100 = 19.04761905](https://img.qammunity.org/2019/formulas/mathematics/middle-school/etuk7nc5deof0rbbubqnjnerevkkez967p.png)
Thus, the profit of each one is:
Calculating we have:
Answer:
To each corresponds:
571.43, 400, 228.57
