Let z be the constant rate of decline in inches of the burning candle. clearly after x minutes the candle will have declined inches. At the rate of z, after x minutes the height y of the candle is given by inches. We know that at minutes the height of the candle is 2.5 inches, so for the given decline rate of z inches per minute, . We solve this expression for the decline rate z, i.e. inches per minute. Our candle height of y inches of the candle after x minutes is given by the expression .
