Answer:

$49,787.16

Step-by-step explanation:

The expression that describes continuous compounding is:

[tex]FV = P*e^{rt}[/tex]

The principal (p) that yields a future value of $1,000,000 at a rate of 7.5% for 40 years is given by:

[tex]1,000,000= P*e^{0.075*40}\\1,000,000=20.0855 P\\P=\$49,787.16[/tex]

The principal value that must be invested is $49,787.16.
