4. Archie, the lead guitarist from a local band, was found dead in the basement's closet of the theater where the band used to practice. He was last seen in the
opposite end of town, getting his hair dyed pink and green. The forensic expert
measures the demarcation line, the line at which the hair dye ends, at 11.5 mm
from the scalp. Assuming his hair grew at the rate of 0.44 mm per day, how
many days ago did he dye his hair? Round your answer to the nearest whole
number. Why do you think it is important to know this information?
