Answer:
The correct option is (B).
Step-by-step explanation:
The exponential decay function is as follows:
Here,
<em>y = </em>final value
<em>a</em> = initial value
<em>r</em> = decay rate
<em>t</em> = time taken
It is provided that:
<em>a = </em>150 mg
<em>r</em> = 9% = 0.09
Then the next hour the amount of caffeine in the body will be:
Then after two hours the amount of caffeine in the body will be:
Similarly after 10 hours the amount of caffeine in the body will be:
Then the inequality representing the range of the exponential function that models this situation is:
Thus, the correct option is (B).
