KJ4UTS one year ago The number of milligrams of a drug initially injected into a person’s bloodstream is 6,120...

1. KJ4UTS

2. anonymous

so initially we have 6120mg of drugs right

3. anonymous

now after one hour how much do we lose?

4. anonymous

4.99% of the original right?

5. KJ4UTS

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

6. anonymous

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

7. anonymous

4.99% is a fraction 4.99/100

8. KJ4UTS

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

9. anonymous

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

10. KJ4UTS

3,066.12

11. anonymous

yep

12. KJ4UTS
