Answer:
Step-by-step explanation:
If his body is breaking down 45% of the medicine, it is losing 100% - 45% = 55%. This means that while he is LOSING 45% of the medicine, he is KEEPING 55% of it. This is an exponential function of the type
where y is the amount of medicine after the increase or decrease (b) of the original amount, a. The number of hours is represented by x.
Our original amount is 840 mg, so a = 840. And if we are losing .45, we are retaining .55, so b = .55. The model for this situation is
If we want to find out how much medicine is left after 5 hours, we sub in a 5 for x and solve for y:
and
y = 840(.0503284375) so
y = 42.2758875 or, rounded to the nearest tenth,
y = 42.3 mg
