$2\mathrm{.}14$ LAB: Driving costs

Driving is expensive. Write a program with a car's gas mileage $($miles$/$gallon$)$ and the cost of gas $($dollars$/$gallon$)$ as floating$-$point input, and output the gas cost for $20$ miles, $75$ miles, and $500$ miles.

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

print$($f$\text{'}\{$your$\_$value$1$:$\mathrm{.}2$f$\}\{$your$\_$value$2$:$\mathrm{.}2$f$\}\{$your$\_$value$3$:$\mathrm{.}2$f$\}\text{'})$

Ex: If the input is:

$25\mathrm{.}0$

$3\mathrm{.}1599$

where the gas mileage is $25\mathrm{.}0$ miles$/$gallon and the cost of gas is $$3\mathrm{.}1599/$gallon$,$ the output is:

$2\mathrm{.}539\mathrm{.}4863\mathrm{.}20$
