Profit Calculation from Ticket Sales

A non-profit organization is planning a fundraising event. They expect to sell tickets for $15 each. If they sell $x$ tickets, the total amount of money raised, $R$, can be represented by the equation:

$$R = 15x$$

Additionally, they have a fixed cost of $200 for the venue. The profit, $P$, from this event can be expressed by the equation:

$$P = R - 200$$

If the organization sells 30 tickets, what will be their profit?
