My program in C++ runs, but does not provide me with my needed ouput, and I cant seem to find my error or what I must change to get the desired output. Please help me find my mistake. Here is my code #include #include using namespace std; int main() { //Declare required variables int unit,discount=0; const int RETAIL = 99; //Prompt for input cout<<"How many units are being purchased? "; cin>>unit; //Negative case while(unit<0){ cout<<"Please input a positive integer value."; cout<<"\nHow many units are being purchased? "; cin>>unit; } //Set discount if(unit>=10 && unit<=19){ discount = 20; }else if(unit>=20 && unit<=49){ discount = 30; }else if(unit>=50 && unit<=99){ discount = 40; }else if(unit>=100){ discount = 50; } //Compute result double price = unit*RETAIL; double final = price - (price*discount/100); cout << fixed << showpoint; cout << setprecision(2); //Output result cout<<"The total cost of the purchase is $"<

cout<<"The total cost of the purchase is $"<<final;
return 0;
}
for my ouput I am meant to get this answer (image attached) but in my code I am not getting an answer that equals half the one in the picture.
