A student team is sizing a school-approved portable phone-charging rental table. A campus survey shows 1,800 students, 55% carry chargers less than once per week, 20% of those students would rent on a long event day at $2, and the team can provide 160 rentals per event. Text exhibit: Capacity funnel titled 'Portable Phone-Charging Rental SOM'. Stages: Campus students 1,800; Students rarely carrying chargers 55% = 990; Event-day rental interest 20% = 198; Rental capacity 160; Price $2; Event SOM revenue $320. Highlight capacity as the limiting stage. Which event SOM revenue is best supported?
