If I'm not mistaken.. the half-life should be 40,750 years.. so
y = 40,750
I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get
20,375.. so one of those should be correct
So this is a lot of work but ghe answers are (fix)
$15.6375, but if rounded up, $15.64, and $15.63 if rounded down
I don't really understand your question , can you rephrase it ?
Do you mean ?5x7 = 455 ?
because then it would be :
455 divided by 7 which equals 65 :)
