A payment of $2,120 was due two years ago, and a payment of $1,100 is due today. What single payment three years from now would be equivalent to these original payments? Assume that money earns 4.5% compounded quarterly.

Two payments of $10,000 and $5,400 are due in 1 year and 2 years, respectively. Calculate the two equal payments that would replace these payments, made in 6 months and in 5 years if money is worth 4.5% compounded quarterly.
