Final answer:

Donna would have to invest $68,745.12 to have $142,300 after 17 years with an interest rate of 3.45% compounded quarterly.

Step-by-step explanation:

To calculate the amount Donna would have to invest, we can use the formula for compound interest:



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



Where:



  • A is the final amount (in this case, $142,300)
  • P is the principal amount (what Donna needs to invest)
  • r is the annual interest rate (3.45%, or 0.0345)
  • n is the number of times interest is compounded per year (quarterly, so 4)
  • t is the number of years (17)



Plugging in the values, we get:



142,300 = P(1 + 0.0345/4)^(4 * 17)



Simplifying, we find that Donna would have to invest approximately $68,745.12 to have $142,300 after 17 years with an interest rate of 3.45% compounded quarterly.
