Answer:
The sum of money received by Ali, Carrie and Bryan is $ 740.

(i) <em>Ali, Carrie and Bryan received a sum of money. </em>
- Ali's money.
- Bryan's money.
- Carrie's money.
(ii) <em>Bryan's money was </em><em> of Ali's money</em>.

After some algebraic handling, we have the following system of linear equations:
(1b)
(2b)
(3b)
The solution of the system is: ,
,
The sum of money is:
The sum of money received by Ali, Carrie and Bryan is $ 740.
Step-by-step explanation:
a = 2
b = 1
c = 4
<h2>Question:</h2>= Solution ,
= 3 × 2 × 4 - 2 + 2 × 1
= 24 - 2 + 2
= 24 + 2 - 2
= 26 - 2
= 24
hence the answer is 24....
