For questions 1-4, use the diagram below: 4,000 3,000 2,000 1,000 100 400 Level of activity (The graph measures level Of activity on the horizontal axis and total benefit and cost in dollars on the vertical axis. Total benefit starts at the origin and increases at a decreasing rate until an activity level of 500, after which it decreases. Total cost starts at the origin and increases at an increasing rate. Total benefit exeds total cost by $ 1000 at an activity level of 100; total benefit is 51500 and total cost is $500. Total benefit exceeds total cost by about $1250 at an activity level of 200: total benefit is $25C)0 and total cost is $1250. The gap between total benefit and total cost shnnks after an activity level Of 200. Total benefit and total cost intersect at around $3750 at an activity level of 350.) At an activity level Of 100, Select one:
