<span> half life i= 78 hours
amount after 78 hours is 395 kg:
395 = 790e^(k*78)
Dividing by 790 and taking natural log
ln (395/790) = (k*78)
-0.6931 = 78k
-0.00888 = k
lets calculate how much is left after 18 hours:
Amount(18)
= 790e^(-0.00888*18)
Amount = 673.301 kg
hope this helps</span>
409,821,735,673.....the value of the 4 in this number is 400 billion
P=amount of money investedr= interest rate percentage in decimal formt=time in yearsa=total money in the account at a time A = P(1 + rt)A/P = 1 + rtA/P - 1 = rtt = ((A/P)-1)/r t = ((5500/1000)-1)/(6.25/100)t = (5.5-1)/0.0625t = 4.5/0.0625 = 72 years It will take 72 years.

Use this equation:
final = original x multiplier^n
Lets calculate the multiplier
5/100 = 1.05
n is the number of years.
Substitute values in:
final = 3500 x 1.05^10
final = 5701.131194
The answer is $5701.13
