Answer:
$477
Step-by-step explanation:
Calculation to determine the surrender charge Sophia had to pay
Using this formula
Surrender charge = [Withdraw all amount - (Free withdraw all % x Account value)] x Surrender charge
Let plug in the formula
Surrender charge= [$13,700 - (0.12 x $70,000)] x 0.09
Surrender charge= ($13,700-$8,400)×0.09
Surrender charge=$5,300×0.09
Surrender charge=$477
Therefore the surrender charge Sophia had to pay is $477
