Jay and his friends have set up a baseball tournament. He can rent a baseball field for a daily charge of $200 and equipment for $150 per day. If he hires independent umpires, he would need to pay $280 for the day. He would arrange to have caps made for each player at a cost of $4 each. If John can get 90 people to participate, what would they have to charge each of them to recover his costs?

LetPrepresent the price per unit.

Revenue = 90P

Total fixed costs = 200 +150 + 280 = 630

90P - (4* 90) -630 = 0

Solve for P.
