Answer:
Faisal receives $241
Ahmed receives $482
Walid receives $723
Step-by-step explanation:
I am going to build a system of equations to solve this question.
We have that:
x is the amount that Faysal received.
y is the amount that Ahmed received.
z is the amount that Walid received.
Ahmed, Walid and Faisal made $1446 profit from selling used books.
This means that

Ahmed to receive double amount of Faisal
This means that 
Walid to receive triple amount of Faisal.
This means that 
So






Faisal receives $241
Ahmed receives $482
Walid receives $723
8
You can divide it to 6 square and a triangle
The triangle is 2
2 + 6 = 8
Let x = our unknown number
10x = 600
Divide by 10 on both sides to isolate the variable x.
x = 600/10
x = 60
600 is 10 times as much as 60.
