The total bill doesn't add up correctly, don't get where I went wrong? Total bill is way off.

#include <iostream> 
#include<cmath>
#include <iomanip> 
#include <string>

using namespace std;


    const float Small = 1.20;
    const float Medium = 1.50;
    const float Large = 1.70;
    const float less_inches = 3.75;
    const float more_inches = 4.00;

int main()
{
        int No_Sand, Sand_size;
        float DrinkCost = 0.0, SandCost = 0.0, total = 0.0;
        float No_Drinks;
        char  Drink_size;
        cout << fixed << showpoint << setprecision(2);

        //Display Menu
        cout << "------------Menu-------------" << endl;
        cout << "Drinks " << endl;
        cout << setfill('.');
        cout << left << setw(15) << "   Small" << right << setw(6) << Small << endl;
        cout << left << setw(15) << "   Medium" << right << setw(6) << Medium << endl;
        cout << left << setw(15) << "   Large" << right << setw(6) << Large << endl;
        cout << "Sandwiches " << endl;
        cout << left << setw(15) << "   10 inches" << right << setw(6) << less_inches << endl;
        cout << left << setw(15) << "   12 inches" << right << setw(6) << more_inches << endl;

        //Ask for how many drinks or sandwiches and the size of drink or sandwich 
        cout << "\t How many drinks: "; 
        cin >> No_Drinks;
        cout << "\t   What size(S=Small, M=Medium, L=Large)? ";
        cin >> Drink_size;
        cout << "\t How many sandwiches? ";
        cin >> No_Sand; 
        cout << "\t   What size(12/10 inches)? ";
        cin >> Sand_size; 

        //Calculate Drink Cost
        switch (Drink_size)
        {
        case 'S': case 's': DrinkCost = No_Drinks * 1.20; break; 
        case 'M': case 'm': DrinkCost = No_Drinks * 1.50; break;
        case 'L': case 'l': DrinkCost = No_Drinks * 1.70; break;
        }

        //Calculate Sandwich cost 
        switch(Sand_size)
        {
        case 10: SandCost = No_Sand * 3.75; break;
        case 12: SandCost = No_Sand * 4.00; break;
        }

        //Calculate total
        total = Drink_size + Sand_size;
        cout << "\t Total bill = " << total << endl;


    //end program
    system("pause");
    return 0;
}

Output:

------------Menu-------------
Drinks
   Small.........1.20
   Medium........1.50
   Large.........1.70
Sandwiches
   10 inches.....3.75
   12 inches.....4.00
         How many drinks: 3
           What size(S=Small, M=Medium, L=Large)? M
         How many sandwiches? 3
           What size(12/10 inches)? 10
         Total bill = 87.00
