**drwls**, Saturday, February 5, 2011 at 6:18amCalculate how much height it loses per hour. Call it m.

m = (18.6 - 12.2)/16 = ___ cm/h

Then solve

(candle height) y = 12.2

= 18.6 - m(t - 11)

using t = 15

It's called interpolation.

After 10 hours of burning, a candle has a height of 24 centimeters. After 27 hours of burning, its height is 20.6 centimeters. What is the height of the candle after 21 hours?
