Answer: $25078
Step-by-step explanation:
Firstly, we'll find the real interest rate which will be:
(1 + R) = (1 + r)(1 + h)
(1 + 10%) = (1 + r)(1 + 4.8%)
(1 + 0.1) = (1 + r)(1 + 0.048)
1.1 = (1 + r)(1.048)
r = 4.96%.
Now the annual deposit will be gotten by using the annuity future value which will be:
3 million = C(1.0496^40-1) / 0.0496
3 million = C(5.3995) / 0.0496
3 million = 119.627C
C = 3 million/119.627
C = 25078
Therefore, the real amount that must be deposited each year to achieve the goal is $25078
