Explanation / Answer

class Sales {
  
// declaring varaibles
String name;
double cost;
int bulk;
int discount;
int sold;
double totalAmount;
double totalDiscount = 0;

// constructor for cost, bulk quantity and the discount
Sales(double c, int b, int d){
cost = c;
bulk = b;
discount = d;
}
  
// setters for bulk, cost and discount
void setBulk(int b){
bulk = b;
}
void setCost(double c){
cost = c;
}
void setDiscount(int d){
discount = d;
}
  
// getters for bulk, cost and discount
int getBulk(){
return bulk;
}
double getCost(){
return cost;
}
int getDiscount(){
return discount;
}
  
// registering a sale by calculating the values for totalDiscount and totalAmount
void registerSale(int n){
sold = n;
if(sold > bulk)
{
totalDiscount = cost*n*discount/100.0;
}
totalAmount = (cost*n) - totalDiscount;
}
  
// displaying the information of sale
void displaySales(){
System.out.println(name);
System.out.println("Number sold: "+sold);
System.out.printf("Total amount: $ %.2f ",totalAmount);
System.out.printf("Total discount: $ %.2f ",totalDiscount);
}
  
// sample runs
public static void main(String[] args) {
Sales item1 = new Sales(2.5, 4, 10);
item1.name = "Shampoo";
item1.registerSale(10);
item1.displaySales();
  
System.out.println();
  
Sales item2 = new Sales(1.99, 20, 15);
item2.name = "Toothpaste";
item2.registerSale(10);
item2.displaySales();
}
}

/* SAMPLE OUTPUT
Shampoo
Number sold: 10
Total amount: $ 22.50
Total discount: $ 2.50

Toothpaste
Number sold: 10
Total amount: $ 19.90
Total discount: $ 0.00
