Sandy is upgrading her internet service. Comcast charges $60 for installation and $50.45 per month of service. AT&T has free installation but charges $57.95 per month. How many months would I have to have cable for to pay the same amount with both companies? Identify the equation that models this situation.
60x + 50.45 = 57.95
60x + 50.45 = 57.95x
60 + 50.45x = 57.95x
60x + 50.45x = 57.95x

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? Identify the equation that models this situation.
12 - 0.5x = 18 - 2x
12 + 0.5x = 18 + 2x
12x - 0.5 = 18x - 2
12 - 6x = 18 - 2x
