The dance committee hired a DJ for the fall dance. The DJ charges $125 per hour plus $55 for an assistant. The committee wants to keep the total cost under $555. What is the maximum amount of hours the DJ will play at the dance?
125x + 55 < 555 Okay, subtract 55 from both sides. 125x < 500 Divide by 125 to isolate the x. 125x < 500 /125 /125 x < 4 The school can have the DJ for less than 4 hours, or for 4 hours. Hope that helps.
