Final answer:
Tipping theory explains why promotions like happy hour and bat night exist; they create an incentive to tip the balance of attendance in favor of the establishment. Without the graphical representation, the exact results of attendance changes starting from 65 or 40 cannot be specified.
Step-by-step explanation:
The concept of tipping theory implies that certain promotions or special events can enhance attendance or sales by providing an extra incentive for customers to choose one option over others. When applied to happy hour at bars or bat night at baseball games, the underlying objective is to increase patronage by offering a temporary advantage such as discounted drinks or a free bat with admission. These strategies aim to reach a tipping point where the increased attendance not justifies the cost of the promotion but also enhances the overall atmosphere, encouraging even more patronage due to the positive feedback loop of social proof and word of mouth.
If initial attendance were at 65, this number might already be above the tipping point, so the promotion would not only be justified but also likely to lead to further increased attendance. Conversely, if initial attendance were at 40, the promotion might serve to increase attendance to or past the tipping point, improving the chance for the event to become self-sustaining in attractiveness due to the same social dynamics. However, without the specific graphic or a detailed description of the tipping points, we cannot precisely determine the end result in either scenario.
