During a power outage, Mason burns candles for light. Each candle was initially 12 inches long. He wants to know how long they will last. The candles burn at a constant rate, and Mason measures them twice and records their height each time in the table:
Number of hours the candle has been lit = 1 1/2 , 4 1/2
Length of candle = 11 1/4 in , 9 3/4 in
