Sasha promised to pay $3000 in 221 years and $5000 in five years. If she replaces those payments with a payment of $4000 in four years and three months and another payment of $6000, and money is worth 10% compounded quarterly, when should she make the second payment of $6000 ? The payment should be made quarters from now. (Round the final answer to two decimal places as needed. Round all intermediate values to six decimal places as needed.)
