Considering the population of U.S. being 323,000,000 we will have the statement:
3 people .................................... 2 cars
323,000,000 people .................. x cars
=>
cars.
Next we will found out the miles driven in one year by all the cars:
215,333,333 * 10000 = 2,153,333,330,000 miles/ year.
2,153,333,330,000 : 365 = 5,899,543,378 miles/ day.
5,899,543,378 : 20 = 294,977,168 gallons.

Answer:
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms.
Step-by-step explanation:
Half life is the time required for an element to decay into half of its initial size. The supplement has a half life of 4 hours means that it decay to half of its size every 4 hours. Therefore there are 6 stages of division in a day.
i.e ×
×
×
×
×
=
The amount of the supplement in Niklas' body after the first dose (first day) can be determined by;
= × 25
= 0.390625 micrograms
He used the supplement daily for 12 days (12th dose), but the amount of the supplement in his body immediately after the 12th dose would be;
amount in his body per day × number of period for complete decay
= 0.390625 × 11
= 4.296875
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms. This is because immediately after the 12th dose, the supplement has not reach its half life.
