E) 52
Kudos if you like!Notice that we need not consider Lyle's portion in the solution. We can just let K = the money REMAINING after Ann has received her portion and go from there.
Our equation will use the fact that, once we remove Bob's portion, we have $32 for Chloe.
So, we get
K - Bob's $ = 32 Bob received 4 dollars plus one-third of what remainedOnce Bob receives $4, the amount remaining is K-4 dollars. So, Bob gets a 1/3 of that as well.
1/3 of K-4 is (K-4)/3
So ALTOGETHER, Bob receives
4 + (K-4)/3 So, our equation becomes:
K - [4 + (K-4)/3 ] = 32 Simplify to get: K - 4 - (K-4)/3 = 32
Multiply both sides by 3 to get: 3K - 12 - K + 4 = 96
Simplify: 2K - 8 = 96
Solve: K = 52
Plug this K-value into
K - Bob's $ = 32 to get: 52 - Bob's $ = 32
So, Bob's $ = 20
