Revenue from Ticket Sales

A community center is planning a fundraiser by selling tickets for an upcoming event. They have established a linear relationship between the number of tickets sold, $$x$$, and the revenue generated, $$R$$, given by the equation:

$$R = 25x - 100$$

Here, the variable $$R$$ represents the total revenue in dollars. They anticipate that if they sell 12 tickets, the revenue will be:

$$R(12) = 25(12) - 100$$

Calculate the amount of revenue they would generate from selling 12 tickets and express your answer in the grid-in format.
