The correct answer is: 5.44 mL
Given That:
The half-life of a certain type of soft drink is 5 h. If you drink 50 mL of this drink, the formula tells the amount of drink left in your system after t hours. How much of the soft drink will be left in your system after 16 hours?
>>>we have given t as 16 hours
>>>Then becomes:
>>>Therefore, the soft drink left out in the stomach is 5.44 ml after 16 hours.
Put t = 16,
y = 50(0.5)
= 5.44 mL
