Answer :

We have the given equation for the remaining Tylenol in her body.

Where n represents the number of hours.

We need to find the remaining Tylenol in her body after 4 hours. Therefore, set n=4.

Replacing on the formula:

[tex]A=400(0.77)^4[/tex][tex]A=14.99[/tex]

The value is rounded to the nearest hundredth.

Hence, Jane will have 14.99 mg's of Tylenol remaining in her body after 4 hours.
