The MediaTex company has noticed when it advertises, it dramatically increases the number of customers who buy its product at seminars. With advertising, MediaTex expects the attendees to buy their product at a price of $$79.$ The cost of renting a place is $$3900/$day$.$ The cost of food and drinks is $$5\mathrm{.}75$ per person $($assume full capacity of $550).$ If MediaTex assumes at a minimum it will sell $125$ units, what would be the upper bound on advertising dollars $($i$.$e$.,$ where would the company break even?$).$
