The VA-tX company has noticed that when it advertises, it dramatically increases the amount of customers who buy its products at seminars. With advertising, it expects to buy the product at a price of $75. Cost of renting a place is $4000/day, utilities included. Moreover, cost of food and drinks is $5/person. If VA-TX assumes at a minimum it will sell 124 units, what would be the upper bound on advertising dollars. (where would company break even)?
