Final answer:

Mrs. Radner must invest 28,750.00 today to have a 30,000 down payment in 50 months.

Step-by-step explanation:

To calculate the amount Mrs. Radner must invest today to have a 30,000 down payment in 50 months, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

  • A is the future value of the investment (30,000)
  • P is the principal amount to be invested (unknown)
  • r is the annual interest rate (3.55%)
  • n is the number of compounding periods per year (4 for quarterly)
  • t is the number of years (50/12)

By substituting the given values into the formula and solving for P, we find that Mrs. Radner must invest approximately 28,750.00 today to have a 30,000 down payment in 50 months.
