I am trying to wake up here..so please be patient..lol.

The candle starts at 16 in....after 30 min the candle is 12 in....this means that the candle lost 4 inches for every 30 min, or 8 inches for every hr.

h (height) ------ t (hours)
12 1/2
8 1
4 1.5
0 2

now lets find your equation..
8t + h = 16
8(1) + 8 = 16
8 + 8 = 16
16 = 16

I am going with 8t + h = 16...but you might want to get a second opinion..I am not completely sure about this.
