Question

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases by about 35% each hour. What level of aspirin (mg) will be in your bloodstream in 4 hours. NEED ANSWER URGENT!!!

Answer 1

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

$A=P(1-r)^t$

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = $200(1-0.35)^4$

$=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg$

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
