A payment stream consists of three payments: $$1,100$ due today, $$1,600$ due $90$ days from today, and $$2,100$ due $220$ days from today. What single payment, $70$ days from today, is economically equivalent to the payment stream if money can be invested at a rate of $3\mathrm{.}6\%?($Use $365$ days a year. Do not round intermediate calculations and round your final answer to $2$ decimal places.$)$
