cin >> order;
// determine discount
if ((order > 10) && (order < 19))
& discount = 20;
else if ( order > 49)
& discount = 30;
else if ( order > 99)
& discount = 40;
else if ( order < 100)
& discount = 50;
// show discount percentage
cout << " your discount on this purchase is" << discount << ".\n";
double total = price * order - discount;
