Question 577
Let's start at the end and work backwards on this one.
 
His favorite charity got $8,000.

With the assumption that the charity and the iguana received the same amount of money, they the iguana also received $8,000.
 
The caddy received the sum of the charity and the iguana, so the caddy received $16,000.
 
The $50,000 for the son and the money for the caddy, iguana, and charity add up to half of the estate, so that comes out to $82,000. 
 
This means that the wife received $82,000 and the total estate was twice that, so the total value of Mr. Stingy's estate was $164,000.
