Tickets to the senior class play cost $7. Production expenses for costumes and sets are $350. The profit (p) will depend on the number of tickets sold (n). Which equation could represent the relationship between the profit and the number of tickets sold? Determine the number of tickets that must be sold to cover expenses.A) p = 7n + 350; 50 tickets B) p = 7n − 350; 50 tickets C) p = 350 − 7n; 5 tickets D) p = 7n − 350; 35 tickets
