Answer: 7:1

Step-by-step explanation:

First off, we see that the contribution was divided into 16 parts (8+5+3). If the tree was $96, 96/16 = $6, so each individual part was $6.

First Person: 3(6) = $18

Second Person: 5(6) = $30

Third Person: 8(6) = $48

We know that after the two friends return the money, the $96 will have been split evenly between all three of them.

96/3 = 32 - each person pays $32 total

Because each person has to pay $32 total, the first person must return $14 and the second person must return $2. This means that the ratio is 14:2 which can be reduced to 7:1.

Person 1: 32-18 = 14

Person 2: 32-30 = 2

Person 3: 48-14-2 = 32. - check to see if we were correct, which we are because after two friends pay 3rd back, their total is also 32 dollars.
