A consultant, after $3$ months of work, reported that the modified B$/$C ratio for a city$-$owned heliport project is $1\mathrm{.}7.$ If the initial cost is $$1\mathrm{.}9$ million and the annual benefits are $$170,000,$ what is the amount of the annual M&O costs used in the calculation? The report stated that a discount rate of $11\%$ per year and an estimated life of $30$ years were used.
