I have to make a program that asks to enter the # of boxes bought. Then it should display the amount of the discount and the total cost of the purchase after the discount. Each box retails for $50. The problem I'm having is connecting the if else then function to the cost.
cout<<" Units sold: ";
cin>> cost;
cout<<"Total cost " << cost;
cost=(cost * 50);
discount = (50 - cost);
if (cost < 5)
cost=(cost * 50);
else if (cost > 5 && cost < 10);
cost=(50 - (50 * 0.2));
else if (cost > 10 && cost < 20)
cost=(50 - (50 * 0.3));
else if (cost > 20 && cost < 30)
cost=(50 - (50 * 0.4));
else if (cost > 30);
cost=(50 -(50 * 0.5));
