Paul and Donna Kelsch are planning a Mediterranean cruise in 3 years and will need $5,500 for the trip. They decide to set up a "sinking fund" savings account for the vacation. They intend to make regular payments at the end of each 3 month period into the account that pays 6% interest compounded quarterly. What periodic sinking fund payment (in $) will allow them to achieve their vacation goal? (Round your answer to the nearest cent.)
