anonymous · Answer

so initially we have 6120mg of drugs right

anonymous · Answer

now after one hour how much do we lose?

anonymous · Answer

4.99% of the original right?

kj4uts · Answer

So would that be 6,120*.499 = 3,053.88?

anonymous · Answer

no. our equation we set up is this

where y is now much drug is remaining and x is the number of hours gone. 

$$y=6120-\frac{ 4.99 }{ 100 }(6120)x$$

anonymous · Answer

4.99% is a fraction 4.99/100

kj4uts · Answer

for x at the end do I plug in 10 for the amount of hours

anonymous · Answer

so just sub 10 into x to get how much drug is present after 10 hours

kj4uts · Answer

3,066.12
