Question

The milligrams of aspirin in a person's body is given by the equation a = 500 ⋅ (3/4)t , where t is the number of hours since the patient took the medicine. How much aspirin will be in the person's body after two hours?

Answer 1

a = 281.25 mg after two hours

Explanation:

Here, we want to get the amount of aspirin that will be present after two hours

what we simply do here is to substitute 2 for t

Thus, we have it that;

a = 500(3/4)^2

a = 500•(0.75)^2

a = 281.25 mg
