Hey here is answer to your question.

#include <iostream>
#include <string>

using namespace std;

// Product name: Fluffy Puff Marshmallows

// Price: $1.99

// Fluffy Puff Marshmallows: $1.39 (with 30% discount)

int main()
{
   string product;
   float price;

   cout << "Product name: ";
   // used getline function because input have
   // white spaces which program cant read unless
   // get line is used
   getline(cin,product);

   cout << "Price: $";
   cin >> price;
   cout << endl;

   cout << product << ": $";
   // used %.2f to print up to 2 decimal points of price
   printf("%.2f",price * 0.7);
   cout << " (with 30% discount)" << endl;

   return 0;
}
