student : yes
student : Skeletal remains had lost 90% of the C-14 they originally contained. Determine the approximate age of the bones. (Round your answer to the nearest whole number.)
student : hello
tutor3 : yes hello but i guess this is a chemistry problem of carbon dating
student : no is from algebra problem
student : i got this from my hw math class
tutor3 : we know the age of a thing is determined by the amount of c-14 is lost from the thong.Thus the approximate age of the bones is 90/100=.9 or =1 (rounded off)
student : ok
student : then how divided by 100
tutor3 : because it says 90% and %of anything means that thing divided by 100
