Hair on a human head grows at about 0.4 mm per day. Calculate the length of a person’s hair if 8 days have passed, and the original hair length is 17 cm.

Let’s use the formula: L (t) = 0.04t + b. (L-hair length, t-time, b-original hair length)
L = 0.04 * 8 + 17 = 0.32 + 17 = 17.32 cm
Answer: 17.32 cm
