An online movie streaming plan charges an annual fee of $45 plus $2.50 per movie watched.  Another plan has no annual fee but charges $3.75 per movie watched.  Write an equation that shows how many movie is the cost of the plans the same.

• 45 + 2.50x = 3.75
• 45x + 2.50 = 3.75x
• 45 + 2.50x = 3.75x
• 45 - 2.50x = 3.75x

A 10 inch candle burns at a rate of 2 inches per hour. A 16 inch candle burns at 4 inches per hour. After how many hours will the 16 inch candle be shorter than the 10 inch candle?

• 10 - 2x < 16 - 4x
• 10 + 2x < 16 + 4x
• 10 + 2x > 16 + 4x
