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? o 4 o 5 o 8 o 12
Answer
Explanation:
Step1: Move terms with x to one - side
Subtract $10x$ from both sides of the equation $120 + 10x=25x$. $120+10x - 10x=25x - 10x$ $120 = 15x$
Step2: Solve for x
Divide both sides of the equation $120 = 15x$ by 15. $x=\frac{120}{15}$ $x = 8$
