Answer:
The stadium's profit margin last month was $267500
Step-by-step explanation:
Amount of money spent on first event = $72000
Amount of money spent second event = $47500
Amount of money spent on third event = $65000
Total money spent on three events = 72000 + 47500 + 65000
= $184500
Fixed expense of stadium on one event = $10000
So, Expense for the three events = 3 × 10000
= $30000
Total money spent on all the events by the stadium = 184500 + 30000
= $214500
Amount earned by the stadium through these three events = $482000
Profit earned = Amount earned - Amount spent
= 482000 - 214500
= $267500
Hence, The stadium's profit margin last month was $267500
