Answer:
$115.20
Step-by-step explanation:
Missing part is "Assume that securitization combined with borrowing and irrational exuberance in Hyperville have driven up the value of existing financial securities at a geometric rate, specifically from $4 to $8 to $16 to $32 to $64 to $128 over a six-year time period. Over the same period, the value of the assets underlying the securities rose at an arithmetic rate from $4 to $6 to $8 to $10 to $12 to $14."
If the underlying assets price fall by $10, then the securities value will fall by a ratio of $10
Value of securities = $128/$10 = $12.80
Decline in value of securities = $128 - $12.80 = $115.20. Thus, the Decline in value of the financial securities is $115.20
