: Hi. Can anyone help me to solve this word problem? I would greatly appreciate it.
1. A drug is eliminated through the body through urine. Suppose that for an initial dose of 10 milligrams the amount A(t) in the body of t hours later is given by A(t) 10(0.8)^t.
Estimate the amount of the drug in the body 8 hours after the initial drug dose. This question is from textbook Alg and trig

A%28t%29+=+10%280.8%29%5Et
Replace 't' with '8'
A%288%29+=+10%280.8%29%5E8
A%288%29+=+1.678
So after 8 hours from taking the initial dose, the amount of drug inside the body is 1.678 mg.
