Answer:
Withdrawal each month = $11,379.01
Step-by-step explanation:
As per the data given in the question,
Value of investment at the time of retirement
= 750 × (((1+(10%÷12))^(30×12) -1) ÷ (10%÷12)) + 250 × (((1+ (6% ÷ 12))^(30×12) -1) ÷ (6%÷12))
= $1,946,494.70
So, we can calculate the withdrawal of each month by using following formula:
Withdrawal each month = $1,946,494.70 ÷ ((1-(1+(5% ÷ 12))^(-25×12)) ÷ (5% ÷ 12))
= $11,379.01
