Final answer:
The amount of money in the account on the night of December 31, 1999, was $18,351,200.
Step-by-step explanation:
To find the amount of money in the account on the night of December 31, 1999, we need to calculate the future value of the $2 million annual payments for 7 years at an interest rate of 4% compounded annually.
Using the formula for compound interest: FV = P(1+r)^n
where FV is the future value, P is the payment or principal, r is the interest rate, and n is the number of periods, we can calculate:
Calculate the value of each payment: $2 million x (1+0.04)^7
= $2 million x 1.3108
= $2,621,600
Calculate the future value by multiplying the value of each payment by the number of payments:
$2,621,600 x 7
= $18,351,200
Therefore, the amount of money in the account on the night of December 31, 1999, was $18,351,200.
