riving is expensive. Write a program with a car's gas milage $($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 by executing

cout $<<$ fixed $<<$ setprecision$(2)$; once before all other cout statements. Note: End with a newline.

Ex: If the input is:

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

where the gas mileage is $20\mathrm{.}0$ miles$/$gallon and the cost of gas is $$3\mathrm{.}1599/$gallon$,$ the output is:

$3\mathrm{.}1611\mathrm{.}8579\mathrm{.}00$ #include

#include $//$For setprecision

using namespace std;

int main$()\{$

double gasMileage, gasCost;

$//$ Input gas mileage and gas cost

cin $>>$ gasMileage $>>$ gasCost;

$//$ Set precision for floating$-$point output

cout $<<$ fixed $<<$ setprecision$(2)$;

$//$ Output gas cost for $20$ miles, $75$ miles, and $500$ miles

cout $<<$ gasMileage $*20\mathrm{.}0*$ gasCost $<<\text{'}\text{'}$;

cout $<<$ gasMileage $*75\mathrm{.}0*$ gasCost $<<\text{'}\text{'}$;

cout $<<$ gasMileage $*500\mathrm{.}0*$ gasCost $<<$ endl;

return $0$;
