5. Doctors can measure the amount of blood in a patient by injecting a known volume of red blood tagged with chromium-51. After allowing the blood to mix, they measure the percentage of tagged cells in a sample of the patient's blood and use a proportion to compute the original blood volume. Chromium-51 has a half-life of 27.7 days. How many days would it take for 70% of the Chromium-51 sample to decay? Round to the nearest tenth.
