To calculate the amount of money Zulemia's grandparents deposited on the day she was born, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where:
A = the final amount of money in the account ($32,349.72)
P = the principal or initial amount of money deposited
r = the annual interest rate (4.27% or 0.0427)
n = the number of times the interest is compounded per year (365, since the interest is compounded daily)
t = the time the money is invested, in years (18)
Substituting the known values into the formula, we get:
$32,349.72 = P(1 + 0.0427/365)^(365*18)
Simplifying this equation and solving for P, we get:
P = $5,000
Therefore, Zulemia's grandparents deposited $5,000 on the day she was born.
