Question

A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk and the profit of each carton of milk vary from farm to farm. Write a program that prompts the user to enter: The total amount of milk produced in the morning. The cost of producing one liter of milk. The profit on each carton of milk. The program then outputs: The number of milk cartons needed to hold milk. Round your answer to the nearest integer. The cost of producing milk. The profit for producing milk.

Please post in C++ and make sure the answer is able to be rounded to the nearest integer.

Answer 1

// C++ program to calculate the total number of cartons of milk produced, total cost of producing the milk and total profit for producing the milk

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

int main()

{

       double milk_per_carton = 3.78; // given amount of liters of milk in one carton

       double total_milk, cost_per_liter, profit_per_carton;

       int num_carton;

       double profit, total_cost;

       // input the total amount of milk produced in liters

       cout<<"Enter the total amount of milk produced in the morning(in liters) : ";

       cin>>total_milk;

       // input of cost of producing one liter of milk

       cout<<"Enter the cost of producing one liter of milk : ";

       cin>>cost_per_liter;

       // input of profit on each carton of milk

       cout<<"Enter the profit on each carton of milk : ";

       cin>>profit_per_carton;

       num_carton =round( total_milk/milk_per_carton); // calculate the number of cartons needed

       profit = (num_carton*profit_per_carton); // calculate the total profit of producing the milk

       total_cost = cost_per_liter*total_milk; // calculate the total cost of producing the milk

      

       // output the number of cartons, total profit of producing the milk and total cost of producing the milk

       cout<<"The number of milk cartons needed to hold milk : "<<num_carton<<endl;

       cout<<"The cost of producing milk : $"<<fixed<<setprecision(2)<<total_cost<<endl;

       cout<<"The profit for producing milk : $"<<fixed<<setprecision(2)<<profit<<endl;

return 0;

}

//end of program

Output:
