Amy and a group of friends have set up a long weekend
softball tournament. The tournament
will be held on Saturday, Sunday, and Monday. They can
rent a softball field for a daily charge of $320 and
equipment for $150 per day. If they hire an independent
umpire (referee/judge), they will need to pay
$250 for each day. They would arrange to have hats made
for each player at a cost of $8 each. If Amy can
get 100 people to participate in the tournament, what price
should be charged for admission to recover
