You can put this solution on YOUR website!
First you need to substitute the numbers they give you. t=1
n=0.5%281%29%5E4%2B3.45%281%29%5E3-96.65%281%29%5E2%2B347.7%281%29 1 raised to any power is 1
n=0.5%281%29%2B3.45%281%29-96.65%281%29%2B347.7%281%29 1 times any number is that number
n=0.5%2B3.45-96.65%2B347.7
n=255 Now you will need to take the orginal dosage minus this to figure how much is still in the blood
400-255=145
