Hello,

An evil genius was present at your birth. Unbeknownst to you or your mom, you were injected with 100 cubic centimeters (cc) of a docile radioactive material as an experiment the moment you were born. You have recently discovered the unauthorized addition and want to know how much of the substance is still left in your body. You craftily figured out the formula for deterioration of the substance and are ready for some answers.The formula to determine the amount of the substance left in your body:

Y is the amount of the foreign substance in your body. The variable, a, represents your current age in years.

Calculate your age to the nearest thousandth. Using this formula, find the amount of the material remaining in your body today rounded to the nearest thousandth. Share your findings with the class.

Here is my classmate's post.

29 years old and 170 days I was born October 28, 1987

170/365 + 29 years = 29.466

Y= 100/a² + 1

100/ (20.466)² + 1

Y= 1.115 cc

How about my brother,My brother's birthday is May 5,1966, Can anyone calculate my brother's ? Thank you .
