The formula p = n*t - e represents profit, p, number of tickets, n, price of tickets, t, and the total expenses, e.
The basic idea of profit is income - expense, or the money you receive minus the money you had to spend in making it happen. The income, or revenue, is the number of tickets sold times the price of the tickets. The expense of making the event happen is given, in this case, as a fixed number, $75. So we plug the numbers we know into the equation and solve for what we don't know.
600 = 350t - 75
add 75 to both sides: 675 = 350t
divide by 350: 675/350 = t
1.93 = t
round up to the nearest quarter and we get the price of tickets t = $2.00
