Mr. Pennypacker left half of his estate to his wife; $40,000 to his daughter; half of what remained to his butler; half of what remained for the care of his favorite dog; and the remaining $6,000 to charity. What was the value of Pennypacker's estate?
6000
6000 x 2 = 12,000
12,000 x 12,000 = 24,000
24,000 + 40,000 = 64,000
64,000 x 2 = $128,000
