We have that during the event the group raised:
[tex]1.62\cdot1000000=1620000[/tex]Or $1,620,000.
There were 790 people that night.
Therefore, we have:
[tex]\frac{1620000}{790}=2050.63[/tex]Then, we have that it was raised, on average, about $2050.63 per person during the charity event.
[We assume here that the average money per capita is the total raised money divided by the total people that attended the charity event.]
