The El Portal Theater is showing a movie to raise money for a local charity. The cost to put on the event is $1840, which includes rent on the theatre and movie, insurance, and wages for the paid attendants. If tickets cost $8 each, then solving the equation 8x=1840 gives the number of tickets they must sell in order to cover their costs. This number is called the break-even point, solve the equation for x to find the break-even point
