Zorah, a musician, pays $120 to have her instrument tuned and $10 per hour for a booth at a fair. She estimates that she earns $25 per hour in tips. The equation can be used to represent the break-even point. 120 + 10x = 25x How many hours, x, will Zorah have to play in order to break even?

Subtracting 10x from the given equation gives
120 = 15x
Then dividing by 15 gives
8 = x

Zorah will have to play 8 hours in order to break even (cover her expenses exactly).
