See attachment for .cpp source files

Program starts here

#include<iostream>

using namespace std;

int main()

{

// Calculate number of ingredient that makes up 48 cookies

float num_sugar = 1.5/48;

float num_butter =1.0/48;

float num_flour = 2.75/48;

//Declare integer variable to get number of cookies from user

int n;

// Prompt user for number of cookies needed

cout<<"Enter number of cookies: ";

cin>>n;

// Calculate equivalent amount of ingredient

num_sugar *= n;

num_butter *= n;

num_flour *= n;

// Display Result

cout<<"You need "<<num_sugar<<" cups of sugar, "<<num_butter<<" cups of butter, and "<<num_flour<<" cups of flour.";

return 0;

}

//End of Program
