#include

#include

using namespace std;

int main$()\{$

int numPeople $=20$;

int numPizzas $=4$;

double totalCost $=14\mathrm{.}95$;

cin $>>$ numPeople;

cin $>>$ numPizzas;

cin $>>$ totalCost;

cout $$ "People: $"$ numPeople $$ endl;

cout $$ "Pizza$($s$)"$ "needed: $"$ ceil$(3\mathrm{.}33)$ endl;

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

cout $$ "Cost for "pizza$($s$)$: $numPeople $*2)*$ totalCost $/10$ endl;

return $0$;
