To cover the cost of hosting the event with 10 people attending, we need to calculate the total cost and then divide it by the number of attendees.
The cost for hosting the event is $200 plus $50 per person attending.
For 10 people attending, the total cost would be $200 + ($50 * 10) = $200 + $500 = $700.
To cover this cost, each attendee would need to be charged $700 / 10 = $70.
Therefore, in order to cover the cost of hosting the event with 10 people attending, you would need to charge each attendee $70
