Answer: the amount to be invested is $249,583.96

Explanation: To determine the amount to be set aside to get $190,000 2 years from now and $120,000 6 years from now.

Using the Effective rate (i) per year: r = 8% per year m = 4 per year

i = r / m = 8% / 4 = 2% per quarter

Calculate the present value: P = -190,000 (1 / (1 + 0.02)8) - 120,000 (1 / (1 + 0.02)16) =-248,583.96

Therefore, the amount to be invested is $249,583.96 at an interest rate of 8% per year compounded quarterly.
