Final answer:
To calculate the present value needed, we use the present value formula. After plugging in the given values, the amount to be invested now is approximately $89,526.48.
Step-by-step explanation:
To determine the present value needed to accumulate a desired amount of $140,000 after 7 years with a 6% interest rate compounded quarterly, we can use the present value formula. The formula is:
PV = FV / (1 + r/n)^nt
Where PV is the present value, FV is the future value, r is the interest rate, n is the number of times compounded per year, and t is the number of years. Plugging in the given values, we have:
PV = $140,000 / (1 + 0.06/4)^(4*7)
Simplifying the expression:
PV ≈ $89,526.48
Therefore, the amount to be invested now, or the present value needed, is approximately $89,526.48.
