Hello,

I need to respond my classmate's posting on the discussion board. I want to know if she did right or not ? Or have different way to calculate ? Thank you very much.

I was born on 10^th of July, 1964.

21 days in July + 31 days in August + 30 days in September + 31 days in Oct + 30 days in Nov + 31 days in Dec + 30 days in Jan + 28 days in Feb + 31 days in March + 12 days in April = 275 days

So I am 52 + 275/365 = 52.753 years old

Y = 100/(a²+1)

Y = 100/(52.753²+1)

Y = 100/(2782.879 + 1)

Y = 100/2783.879

Y = 0.036 cc

I have 0.017 cc less radioactive substance in my body
