Answer 2

Answer:

#include<iostream>

using namespace std;

int main()

{

double i,j,b,a;

cin>>i>>j;

a=2*j;

b=((j/100)*50);

if(i<=2)

{

  cout<<(a-b);

}

else if(i==3)

{

  cout<<(2*j);

}

else

{

  cout<<"Number of items is more";

}

}

Explanation:

we doubled the heating than subtracted 50%
