The milligram of aspirin in a person's body is given by the function a(t)=500. (3/4)^t where t is the the number of hours since the patient took the medicine.

How many milligrams of aspirin will be in the patient's body after 2 hours? (answer to 2 decimals)

• 282.231

• 281.25

• 281

• 281.1

The milligram of aspirin in a person's body is given by the function a(t)=500. (3/4)^t where t is the the number of hours since the patient took the medicine.

In the function rule, What does 500 tell us about the situation?

• There was 500 mg outside the body when the aspirin was taken.

• There were 500 mg of aspirin in the person's body when she took the aspirin.

• 500 represents the time it took for the aspirin to spread in the body.

• 500 represents the factor by which the medicine was spreading in the body.

The milligram of aspirin in a person's body is given by the function a(t)=500. (3/4)^t where t is the the number of hours since the patient took the medicine.

In the function rule, What does 3/4 tell us about the situation?.

• The aspirin in the persons body decreases by 3/4

• The aspirin in the person's body increases by 1/4

• Each hour, the amount of aspirin in the person's body is multiplied by 3/4 or decreased by 1/4
