Answer:
Let's work backward to find out how much money was originally in the gentleman's estate.
He leaves $8,000 to the local elementary school.
After this donation, the remaining estate is 0.5 (half) of what it was.
He donates half of what is now remaining to his church.
This means the amount before the church donation was $8,000 * 2 = $16,000.
He leaves half of the remaining money to his best friend.
Before the best friend's share, the estate was $16,000 * 2 = $32,000.
He left his son $50,000.
Before leaving his son's share, the estate was $32,000 + $50,000 = $82,000.
He left half of his estate to his wife.
Therefore, the original estate was $82,000 * 2 = $164,000.
So, the gentleman originally had $164,000 in his estate.
