Question

A candle is lit and burns until it is burned out, and the length of the candle changes at a constant rate of -1.2 inches per hour. 2 hours after the candle was lit the candle is 10.6 inches long. Write a formula that expresses the remaining length of the candle in inches, L, in terms of the number of hours t that have elapsed since the candle was lit

Answer 1

L = 13 -1.2t inches

L=10.6 = 13-1.2(2) = 13 -2.4 = 10.6

Answer 2

The candle started at 10.6 + 2(1.2) or 13 inches.

L = 13 - 1.2t
