Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.
Step-by-step explanation:
Let's say that Justin has x dollars.
Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.
Since Cho has 2 times of what Justin has, Cho has 2x dollars.
In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.
x + (x - 5) + 2x = 79
So: 4x - 5 = 79
So 4x = 84
So x = 21
Therefore Justin has 21 dollars
Since Raina has 5 dollars less than Justin, Raina has 16 dollars
Since Cho has 2 times of Justin, Cho has 42 dollars
