John is making an experiment for class. The equation H=-0.3m+16.4 models the relationship between the height of a candle in centimeters. H is the time the candle is burning and M is minutes. Find the height of the candle, in centimeters, if the time the candle is burning is 29 minutes.

Step-by-step explanation:

Remark

At the beginning of the experiment the time (in minutes) is zero. That means that the -0.3*m term disappears. The point of the remark is that the candle's height to begin with is 16.4 cm

Given

m = 29 min

Solution

H = - 0.3*m + 16.4

H = - 0.3*29 + 16.4

H = - 8.7 + 16.4

H = 8.8 cm
