Question 1201882: Please help me solve this word problem it is due tomorrow
An element decays at the rate of S(t) = se^-0.032t, where s is the initial amount in grams and t is the time in years since this initial amount was present. If you have a 87-gram piece of this element, how many grams will you have 5 years from now? Round your answer to the nearest tenth of a gram.

You can put this solution on YOUR website!
cross%28S%28t%29+=+se%5E-0.032t%29
S(t) = se^-0.032t
S%28t%29+=+se%5E%28-0.032t%29

s is given, and t is given.

Simply plug in the given values and follow the formula; evaluate S.
S%285%29=87%2Ae%5E%28-0.032%2A5%29
