$20\mathrm{.}1$ LAB: Input and formatted output: Caffeine levels

A half$-$life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half$-$life of about $6$ hours in humans. Given caffeine amount $($in mg$)$ as input, output the caffeine level after $6,12,$ and $24$ hours. Use a string formatting expression with conversion specifiers to output the caffeine amount as floating$-$point numbers.

Output each floating$-$point value with two digits after the decimal point, which can be achieved as follows:

print$($f$\text{'}\backslash \{$your$\_$value:$\mathrm{.}2$f$\backslash \}\text{'})$

Ex: If the input is:

$\backslash [$

$100$

$\backslash ]$

the output is:

$```$

After $6$ hours: $50\mathrm{.}00$ mg

After $12$ hours: $25\mathrm{.}00$ mg

After $24$ hours: $6\mathrm{.}25$ mg

$```$

Note: A cup of coffee has about $100$ mg $.$ A soda has about $40$ mg $.$ An "energy" drink $($a misnomer$)$ has between $100$ mg and $200$ mg $.$
