$2\mathrm{.}14$ LAB: Driving costs $-$ use python$/$IDLE

Driving is expensive. Write a program with a car's miles$/$gallon and gas dollars$/$gallon $($both floats$)$ as 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$(\text{'}\{$:$\mathrm{.}2f\}\{$:$\mathrm{.}2f\}\{$:$\mathrm{.}2f{\}}^{\text{'}}$ format$($your$\_$value$1,$ your$\_$value$2,$ your$\_$value $3))$

Ex: If the input is:

$20\mathrm{.}03\mathrm{.}1599$

Then the output is:

$3\mathrm{.}16,11\mathrm{.}85,79\mathrm{.}00$
