Sandy is upgrading her internet service. Fast internet charges $60 for installation and $50.45 per month. Quick internet has free installation but charges $50.75 per month. How many months would I have to have cable for to pay the same amount with both companies? 

• 60x + 50.45 = 50.75
• 60x + 50.45 = 50.75x
• 60 + 50.45x = 50.75x
• 60x + 50.45x = 50.75x

A twelve inch candle and an 18 inch candle are lit at 6pm. The 12 inch candle burns 0.5 inches every hour. The 18 inch candle burns two inches every hour. At what time will the two candles be the same height? Write an equation.

• 12 - 0.5x = 18 - 2x
• 12 + 0.5x = 18 + 2x
• 12x - 0.5 = 18x - 2
• 12 - 6x = 18 - 2x

The school cafeteria seats 250 students. 203 students are already seated. Write and solve an inequality that represents the additional number of students that can be seated.

• 203 + s ≤ 250; 47 students
• 250 - 203 = x; 47 students
• 203 + s < 250; 47 students
• x + 203 = 250; 47 students
