Starting in $2024,$ the regional government offices, health departments, and public libraries in the city of Boulder, Colorado, will adopt a $9-$hour$/$day$,4-$day workweek from the beginning of June through the end of October. The shortened workweek will affect $30\%$ of the city$$s $8000$ employees and will save $$55,000$ per month for those $5$ months, due to decreased electricity, water, and maintenance costs. If this work schedule persists for the next $15$ years, what is the future value of the savings at the end of that period $($i$.$e$.,$ end of year $2039)?$ Assume an interest rate of $0\mathrm{.}6\%$ per month.
