Question 1103350
they spent 224.
they sell tickets at 3 dollars apiece.
n is the number of tickets.


profit = revenue - expenses.


revenue = 3 * n
expenses = 224.
profit = p


your equation is p = 3 * n - 224.


replace p with whatever variable you use to represent profit and you should be ok.


they will start to make a profit after they sell about 75 tickets.
thaat's their break even point.


you solve for that by setting p = 0.


when p = 0, the equation becomes 0 = 3 *n -224
add 224 to both sides of this equation to get 224 = 3 * n
divide both sides of this equation by 3 to get 224 / 3 = n
solve for n to get n = 224/3 = 74.67 rounded to 2 decimal places.


when they sell 74 tickets, they still haven't made a profit.
when they sell 75 tickets or more, they are in the green.
